+This accompanies the teubner bundle version 3.0 dated April 2010.

+The bundle has the status of author maintained.
 
-File teubner-doc.pdf  is  the  documentation  file  that  shows what can
-be done with this  extension  package  and  displays  several  examples.
-The first edition of this file could not resort to scalable type 1 Greek
-fonts  (2001);  by  the  end  of 2002 such fonts were available on CTAN,
-therefore this edition not only reports  the enhancements  introduced in
-version 2.0 but also it displays and prints perfectly.
+The main purpose of this bundle is to provide classical philologists with some
+means for typesetting their documents that usually contain very specific notation.
 
-In  order  to  use  this  extension  package  with  LaTeX  you  have  to
-install  it.  Run  teubner.ins  through  LaTeX;  the  generated  file is
-teubner.sty and must be  moved  where  TeX  the  program  can  find  it.
-This  depends  very  much  on  your  particular  implementation  of  the
-TeX   system,   but   if   your  system  copes  with  the  standard  TeX
-directory  structure  and   with   a   multiplicity  of  different  root
-directory   structures,   you   probably   have   a   localtexmf   root,
-containing  a  tex  directory   which   on   turn   contains   a   latex
-directory.   Under   the   latter  directory  create  a  new  directory,
-named, say, teubner, and move there teubner.sty.
+This new version allows the typesetter to use both "italic" shapes: the Olga-like
+and the Lipsian-like ones; it contains extended accent macros that avoid the kerning
+problems that arise with the ligature mechanism embedded in the LGR encoded default
+CBgreek fonts; is compatible with the use of different scalable Latin Type~1 fonts; contains new designs for the horizontally stretchable markers, et cetera.
 
-I suggest  you  to  create  a  directory  teubner  in  the doc directory
-of   the   localtexmf   rooted   structure  and    move    there    both
-teubner-doc.pdf   and   teubner.dvi   that  you  get  by  running  LaTeX
-directly on teubner.dtx.
+The byproducts of the installation consists in a LGRaccents-gyphs.def file that might
+be separately input and used also without the teubner bundle. Moreover this new
+version generates on the fly the necessary font description files necessary to use the
+LGR encoded Greek fonts with non TeX standard PostScript fonts; for example it
+automatically generates the necessary .fd files if using the TX or the PX fonts; with
+other Type 1 fonts the necessary .fd files require manual intervention, which simply 
+means giving a suitable command from within another open file that loads teubner.
 
-For what concerns the fonts, I suggest you download the type 1 pdf fonts
-from CTAN: there you can get also the tfm files and  the sources for all
-the Greek and metric symbol files; in case you prefer to use the  raster
-fonts generated  by METAFONT  you can download  also the source METAFONT
-files.
-
-
-In  the  texmf  rooted  directory   structure  there should  be  a  file
-under fontname, named  special.map;  edit such file and possibly add the
-line
-
-gmtr            public          teubner
-
-possibly preceded by a comment line of the form
-
-@c Metric symbols font
-
-This last task is not  really  necessary,  but  it  is  useful,  because
-the  generated  tfm  and  pixel  files  will  be automatically deposited
-in the proper directories, with no confusion with other fonts.
-
-Another important  step  is  to  control  that  you  have  the latest CB
-Greek fonts; even  if  you  got  them  installed  with  the  TeX  system
-installation   program,   may   be  they  are  not  the latest  version,
-compatible  with  this  extension   package.  Control  your  cbgreek.txt
-file and  at  the  end  of  the  file  there  is  its  date;  this  date
-should be not earlier than 15th of August 2002.  If the date  is earlier
-than this, connect to CTAN and  download  the latest version of  the  CB
-Greek  fonts  both  in  METAFONT  and  in pfb  type 1 format. Follow the
-instructions  for inserting  the proper files in the proper directories,
-and for adding the proper  map file  to the configuration files of dvips
-and  pdfLaTeX.   If you  already  had the  metric tfm files, remember to
-delete  them  in order  to have  them generated  on the fly  by LaTeX or
-pdfLaTeX, or download the newer tfm files from CTAN.
-
-
-Another question you might ask yourself:  is my TeX system complete  and
-up to date? The fact you installed a TeX system and you did not have the
-CB fonts may be an index that you still have the babel package locked at
-a  version  number  earlier than 3.7. I suggest you to upgrade  your TeX
-system to the most up to date one you can find on CTAN.
-
-After all these steps are done,  you  are  ready  to  use  your  teubner
-extensions;  it  will  not  be  easy  at  the  beginning,  because there
-are  hundreds  of  new  commands.  Be  sure  to have  already thoroughly
-read the documentation  file  teubner-doc.pdf  and  that  you  have  the
-hard   copy  close  to  you.  Remember  though  that  most  commands are
-latin  names  or   abbreviations   that   should   be  familiar  to  any
-philologist  specialized  in   classical/ancient   European   languages,
-such as classical Greek, classical Latin, et cetera.
-
-This   set   of   extension   commands   has   been  tested  in  several
-documents; nevertheless I  prepared  them  as  a  hobby,  in the hope of
-helping a  philologist  friend.  I  hope  this  package  may  be  useful
-also  to  you,  but  I  must  disclaim  any  liability  for any unwanted
-results you might  get,  including  the  worst  possible  things that my
-happen to anybody working  with  a  computer.  I  will  not  write  down
-any   strong   disclaimer   sentence  in  capital  letters,  because  it
-should  be  absolutely  evident   that   I   did  something  I  consider
-useful,  but is up  to  you  to  decide  to  use  it  and  to  face  the
-consequences   (...   which  nevertheless  I  hope  they  are  what  you
-expected).
-
-If you find  this  package  of  some  utility  and  you find some errors
-and/or    some    glitches,    please     write     me     by     e-mail
-(claudio.beccari@polito.it). If you'd like  me  to  realize  some  other
-commands,  please  send  me  by  e-mail  your  request  together  with a
-scanned image containing the  visual  result  you'd  like  to obtain.  I
-do  not  guarantee  I'll  be  able  to  satisfy  your  request, but I'll
-give it a try. In  any  case  don't  ask  things  LaTeX can't do; and if
-you use LaTeX, you know what are its pros and cons.
-
-Happy philological LaTeXing!
+Please, be sure to work with a 2010 updated collection of the CBgreek fonts.

+
+
+This bundle contains the following files

+teubner.txt          this file

+teubner.ins          installation file
+teubner-doc.pdf      documentation file
+
+File teubner-doc.pdf  is the documentation file  that  shows what can be 
+done with this extension package and displays several examples.
+Version 3.x of the teubner package contains many new enhancements, among 
+which  it's worth  noting  the new  extended  accent macros  (that avoid 
+kerning  problems that show up using the ligature mechanism) and the new 
+macros  that allow  to use  the LGR encoded CBgreek fonts in conjunction 
+with other PostScript scalable fonts;  the compatibility  with the Times 
+eXtended  and  the  Palatino  eXtended  fonts,  accessible  through  the 
+packages  txfonts and pxfonts,  are already built in;  the compatibility 
+with  the Latin  Modern  fonts was already available with version 2.x of 
+the teubner package.
+
+In  order  to  use  this  extension  package  with  LaTeX  you  have  to
+install  it.  May be the  very installation of your  (recent) TeX system 
+distribution  already  provided  for  it;  may  be  your  TeX  system is 
+configured  to load  missing  packages  on the fly.  In any case you can 
+check and possibly run your Package Manager (with MiKTeX follow the path 
+Programs|MiKTeX Settings|Packages;   with TeXlive and MacTeX   (if their 
+installation  configuration was not the default one,  that is a complete
+installation) run tlmgr).  If you feel more comfortable to do everything 
+by yourself and/or want to make a personal installation, run teubner.ins
+through  LaTeX;  the  generated  files are  teubner.sty  and LGRaccents-
+glyphs.def; they must be moved where TeX-the-program can find them. This 
+depends very much on your particular  implementation  of the TeX system, 
+but if your system copes with the standard TeX directory  structure  and   
+with a multiplicity of different root directory structures, you probably   
+have a localtexmf root, or a /texmmf in your Home directory containing a 
+TeX directory which on turn contains a latex directory. Under the latter  
+one create a new directory named, say, teubner and move there teubner.sty 
+and LGRaccents-glyphs.def.
+
+I suggest you to create  a  directory  teubner  in  the doc directory of
+the locally rooted structure  and move there  both teubner-doc.pdf   and
+teubner.pdf  that you  get  by running pdflatex directly on teubner.dtx.
+
+For what concerns fonts,  they should already be installed with a recent 
+TeX system distribution; this means that there are already all the files 
+TeX-the-program needs in order to do its work; there is one point, though, 
+that requires full attention;  the default  installation  loads only the 
+PostScript  fonts in size 10pt;  all other  sizes  are are  obtained  by 
+reducing or enlarging  that single size.  The teubner package copes with 
+this situation if you specify the "10pt" option when calling this package, 
+but if you want to have perfect optical sizes,  then you should download 
+from  CTAN  the full  collection  and install it in your  computer.  The 
+details  for this installation  require you read  with due attention the 
+instructions  that  come  with  your  TeX system distribution;  it's not 
+difficult,  but it requires to be very careful at every step.  Remember,  
+though, that your Package Manager can do all the work for you.
+
+It's important  to control that you have the latest CBgreek fonts;  even  
+if you got them pre-installed with  your TeX system distribution, may be  
+they  are  not  the latest  version. The full collection has been redone 
+in the year 2007; the reduced collection is a subset of the full one. 
+Earlier distributions, dated at least 2002, might be compatible;  if you 
+get something strange is happening with the CBgreek fonts, verify if your 
+fonts are up to date.
+
+Another question you might ask yourself:  is my TeX system complete  and
+up to date? The fact you installed a TeX system and you did not have the
+CB fonts may be an index that you still have the babel package locked at
+a  version  number  earlier than 3.7. I suggest you to upgrade  your TeX
+system to the most up to date one you can find on CTAN.
+
+Connected to this point there is the question of the updated metric files 
+related  to the Lipsian  fonts; if your TeX system distribution has been 
+updated  to what  is available  on CTAN  by May 2010,  your distribution 
+already  contains the updated tfm files.  Otherwise, please, update your
+CBgreek fonts.
+
+After all these steps are done,  you  are  ready  to  use  your  teubner
+extensions;  it will not be  easy at the beginning,  because  there  are 
+hundreds  of new commands.  Be sure to have already thoroughly read  the 
+documentation file teubner-doc.pdf and that you have the hard copy close 
+to you. 
+
+Remember,  though,  that most commands  are Latin names or abbreviations 
+that  should  be familiar  to any philologist  specialized in classical/
+ancient European languages, such as classical Greek, Latin, et cetera.
+
+This set of extension  commands  has been tested  in several  documents;
+nevertheless I prepared them as a hobby, trying to help a friend philolo-
+gist. I hope this package may be useful also to you, but I must disclaim 
+any liability for any unwanted results you might get, including the worst  
+possible things that may happen to anybody using a computer.  
+
+I will not write down any strong disclaimer sentence in capital letters,  
+because it should be absolutely evident that I did something  I consider
+useful,  but is up to you  to decide to use it and face the consequences
+(... which nevertheless I hope they are what you expected).

+% permission to use his macros, that I adapted to the conventions used within this
+% file. These macros are saved into the definition file |LGRaccent-glyph.def|, so that it can be used also without the |teubner| package, fore example for typesetting without setting the \emph{polytoniko} language attribute.
+%

+% critical way the problems connected with the LGR encoded fonts and the Unicode

+% This kludge is necessary for all fonts that have description files that use the
+% |\EC@family| command for describing the available shapes and sizes; in practice
+% this happens only with the EC fonts, even when the \texttt{cm-super} scalable
+% implementation is used. For using the Latin Modern fonts (LM) new specific font
+% description files for the CB fonts are part of the \babel\ package, so this
+% problem does not exist; when using other fonts, such as the TX, PX, ZE,~\dots,
+% other kludges are necessary, because their font family names are different from
+% those normally used with \TeX: |cmr| for serifed fonts, |cmss| for sanserif ones,
+% and |cmtt| for monospaced ones.\footnote{Even the Latin Modern fonts have
+% different family names, but, due to their importance, specific font description
+% files have been added to the \babel\ package. The Lm fonts are more comfortable
+% than the EC ones, when scalable fonts are to be used, because they are
+% continuously scalable and download into the produced files less font files than
+% the EC o cm-super ones. Unless specifically requested, the LM fonts should always
+% be preferred to the EC and cm-super ones. When using the LM fonts, its better to
+% use the full collection of the CB fonts, although the CB font description files
+% are compatible with the single 10\,pt size.}
+%
+% Notice that when using, for example, the TX fonts and no kludge is available, the
+% CB fonts are loaded only as the ``error font'', since the TX fonts have different
+% family names than the CB ones; in many cases this might pass un-noticed, but if
+% real Greek text in different shapes and series has to be typeset, the unaware
+% typesetter might get crazy trying to force shape and series changes in the Greek
+% text; it would not be impossible, but it would be very, very boring. In any case
+% see in the sequel for the implemented kludges in order to run successful
+% compilations also with non standard \TeX\ system fonts.

+% the |\n@xt| macro equivalent to |\iftrue|, otherwise it sets it to |\iffalse|. In
+% order to succeed, it requires to analize the first two letters of the default
+% family name; if these letters form one of the sequences |cm| or |lm|, the CM or

+% The other macro |\ifFamily| uses the previous macro and according to the test
+% result, possibly runs the |\substitutefontfamily| macro that, if
+% necessary, creates the description file that map the specified family font
+% description file to the second specified font family, both connected to the LGR
+% encoding. Therefore, after these font definition files exist, \LaTeX\ can fetch
+% the Greek fonts by way of substitution. Let's explain again: if you specify
+% \begin{verbatim}
+% \Lispsiantrue\ifFamuly{pxr}{lmr}\Lipsianfalse
+% \end{verbatim}
+% you state that you want to run the macro on the serifed Palatino font family, by
+% associating the |pxr| family to the |lmr| one\footnote{If you have the full CB
+% Greek font collection it's more convenient to map the missing fonts to the Latin
+% Modern Greek ones, while if you need to use the \emph{10pt} option, you'd better
+% map the missing family to the ordinary Computer Modern ones; the actual fonts are
+% the same, but the latter font definition files cope with the \emph{10pt} option,
+% while the former don't.}; by specifying |\Lipsiantrue| you state that you want to
+% create entries also for the Lipsian series and shape; afterwards you reset
+% |\Lipsianfalse| in order to avoid that other call of that macro on non serifed or
+% monospaced fonts try to create entries that in any case do not exist: the Lipsian
+% font comes only as a serifed font!. In this way, if you are using Palatino fonts
+% through the \textsf{pxpackage}, the |teubner| macros provide to create the
+% necessary font description files so that while you are typesetting in medium
+% normal Latin Palatino and you switch to Greek, the built in macros change the
+% encoding to LGR; The LGR Palatino serifed medium normal Greek font does not exist,
+% but that family, series and shape are mapped by the font description file to the
+% corresponding LGR encoded Latin Modern CB fonts in medium series and normal shape,
+% and typesetting goes on with the rigth Greek fonts.

+% You don't actually need to use that macro for the Times or the Palatino eXtended

+% \textsf{pxfonts}, because a hook is set up so that ``at begin document'' the
+% loading of those packages is tested, and if the test is true, the necessary font
+% description files are possibly created. If you load the Tymes or the Palatino or
+% any other non standard font by means of other packages, it's up to you to issue
+% the |\substitutefontfamily| macro right after calling that font package and by
+% using the correct family names; similarly you might substitute the new Latin font
+% family names to other Greek font family names, if you have other fonts available.
+% At the same time at begin document we memorize the name and encoding of the Latin
+% font used for the default language, so that when returning to Latin font
+% typesetting after Greek font typesetting, the proper language typesetting rules
+% and encoding are restored.

+% |\lishape| is the normal declaration, modeled on the other similar macros in the
+% \LaTeX\ kernel, made up to chose the Lipsian shape. Nevertheless since it is a
+% light character, if it must blend well with the other PostScript fonts, not only
+% the CM and LM, but also the other ones available for typesetting with the \TeX\ 
+% system, it is necessary to chose the |b| (bold) series in place of the |m|
+% (medium) one, while maintaining the |bx| (bold extended) series when the other
+% fonts are set with the blacker and larger series. This is why the |\lishape|
+% declaration is a little more complicate than normal, since it has to test the
+% value of the current series. The text command |\textli| matches the similar
+% commands for Latin fonts. But the |\lishape| declaration is used also within the
+% more complicated macros for declaring or setting the Lipsian font.
+%
+% |\Lipsiakostext| is a \emph{declaration} stating that from now on

+% \subsection{Service macros}
 % Now we start the specific additions introduced with this package.
 %
-% \begin{macro}{\numero}
-% We define a short macro |\numero| used to strip off the pt part of a dimension value
-% as displayed by \TeX\ itself; this service macro is going to be used quite a lot for
-% getting the font slant per point parameter so as to be able to put in their correct
-% position various signs over or under other signs.

-}

-% \end{macro}
-%
+% \begin{macro}{\strip@pt}
+% The \LaTeX\ kernel has the macro |\strip@pt| that strips off the pt part from the
+% expanded value of a dimension register name and makes available the measure in pt
+% of the contained length (the register contains the length measure in scaled
+% points; the expansion performed by \TeX\ with the command |\the| converts the
+% scaled points to printer points and shows the result with a string of decimal
+% digits with, possibly, a decimal fraction); its argument is supposed
+% to be a dimension register name, not its expanded contents. The |\strip@pt|
+% command eliminates the decimal point and the fractional part if the latter is
+% nought.
 % With the help of such service macro we are going to define a certain number of
 % ``lift accent'' macros or ``put cedilla'' macros that work with both upright and
 % slanted fonts, although they contain different parameters for Latin compared to
 % Greek alphabets.
-% \begin{macro}{\lift@accent} The first ``lift accent'' macro just puts an accent over
-% a letter, without inserting any space between them; the first argument is the accent

-% All these accent like and cedilla like macros will be extensively used in the following
-% definitions.
+%
+% \subsection{Extended accent definitions}
+% We will use those service macros in the definition of several accent like macros
+% that keep all the intricacies away from the user. Meanwhile we input from
+% a separate file |LGRaccent-glyph.def| a whole set of extended accent macros
+% slightly adapted from those contained in G\"unter  Milde's definition file.
+% In particular the \LaTeX\ kernel macros are used in order to declare accents,
+% composite glyphs, composite commands, and the like; these are used as the default
+% definitions; afterwards other definitions will be given that work when these
+% composite macros don't work.
+% In other words, while |\~| and |u| in Greek form the composite glyph ``upsilon
+% with circumflex'' that exists in the Greek font table, the same macro |\~| and the
+% letter |k| produce the  superposition of a circumflex on top of a ``kappa'' glyph,
+% since this glyph does not exist in the Greek font table.
+% Notice that all these declarations are restricted to the Greek font encoding so
+% they are usable only when such font is in force. See the |teubner-doc.pdf| file
+% for more details concerning the usefulness of the extended accent macros vs.\ the
+% ligature mechanism.
+% 
+%    \begin{macrocode}
+\input{LGRaccents-glyphs.def}
+%    \end{macrocode}
+%
+% \subsection{Special accent macros}
+% Now we come back to the ``accent like'' and ``cedilla like'' general macros we
+% defined above, and that  will be extensively used in the following definitions.
+% Note that for what the circumflex is concerned, when |teubner| is in effect it is
+% not defined as an active character and does not work as a non breaking space. The
+% command |\~| and its equivalent |\GRcirc| is just an accent macro; how do you put
+% a non breaking space in a Greek context? By simply using the \LaTeX\ kernel macro
+% |\nobreakspace|; when typesetting with non-Greek fonts the |~| is certainly handy
+% to insert a non breaking space (a tie), but for polytonic Greek spelling in the
+% past 15 years or so the Greek language definition file has always used the |~|
+% sign a a letter, not as an active character. If you look in the \babel\ package
+% documentation related to the Greek language, you find that for what concerns the
+% |~| with polytonic spelling a number ot ``dirty tricks'' have been used, but
+% nothing has been done to replace the ``tie'' function of this character when
+% typesetting in languages that use the Latin script; the only action related to
+% this point has been to redefine the kernel macros for typesetting figure and table
+% captions so as to substitute the |~| character with its explicit definition
+% |\nobreakspace|. It is necessary to do the same when this package is used,
+% although a shorter command |\nbs| is provided in order to simplify the input
+% keying.

+%
+% Notice that the following code is subject to the boolean variabale |GlyphNames|
+% which is set to true by default, just fort compatibility with the past; I suggest
+% to use the \emph{NoGlyphNames} when typesetting new documents, since the glyphs
+% are more asily specified by means of the extended accent macros that are also less
+% restricted in their names; for a letter marked with a smooth breath and an acute
+% accent you can indifferently type before the letter one of the following |\>\'|,
+% |\>'|, |\'\>|, |\'>| at your choice. Moreover you can always postfix the mark for
+% the iota subscribed at the right of the letter, without any need o memorising
+% complicated names.

+% |trace| package is loaded; this package give access to the macros |\traceon| and

+% workings need not be logged down.
+%
+% If the user needs to trace something in order to spot errors, s/he is invited to

+% It's true that Apostolos Siropoulos wrote also the |athnum.sty| extension package
+% in order to typeset integer numbers with the Athenian or Attic notation; this
+% representation of integer strictly positive integers was similar in a way to the
+% Roman notation, based on a biquinalry representation of decimal digits (taking
+% into account that there was not a symbol for zero) so as the Romans had the
+% symbols for 1, 5, 10, 50, 100, 500 and 1000 (I, V, X, L, C, D, M) the Attic
+% notation has symbols for the same sequence of decimal values extended with 
+% 10\,000 and 50\,000. While typesetting philological texts in Greek it might be
+% necessary to use also the Attic notation. % As the original Roman notation used
+% to be purely additive (i.e.\ 9\,=\,VIIII), so is the Attic notation.
+%
+%\begin{macro}{\AtticNumeral}
+%\begin{macro}{\AtticCycl@}
+% Therefore another conversion macro was devised that receives the value to be
+% converted as its argument and checks that it falls between the boundaries;
+% actually the lower boundary is zero, while the upper boundary was chosen to be
+% 99\,999, for no other reason that the lack of further symbols, beyond the value
+% 50\,000, would force to long sequences of identical symbols that are difficult
+% to read.  The |athnum.sty| package allows to extend this range to 249\,9999;
+% should it be necessary, the user is invited to load that package and its
+% transformation command |\athnum|.
+%
+% The user command |\AtticNumeral| is very simple, but it must be preceded by the
+% definitions of the quinary symbols for 50, 500, 5000, and 50\,000; such symbols
+% are present in all the CB Greek fonts in all sizes, series and shapes; therefore

+%    \end{macrocode}
+% \subsection{First set of extended accent definitions}
+% These macros were originally defined by Guenter Milde
+% in his file lgrenc-accents.def version 3.2 dated 2008-06-17
+% and released under the LPPL LaTeX Project Public License
+% version 1.3 or ay later version.
+% 
+% These macros were slightly modified by Claudio Beccari
+% in this file, version 1.0 of 2010-04-13, in order to adapt them
+% to the teubner.sty package, but they can be used independently of 
+% this package.
+%
+% This modified version is released again under the LPPL license
+% version 1.3c or any later version.
+%
+% These definitions are a modest variation of the standard LGR
+% encoded ligature set, in the sense that they don't rely on
+% ligatures but on accent  and composite text macros that address
+% directly the accented glyphs.
+%
+% For example, if alpha with smooth spirit, acute accent and iota
+% subscribed has to be inserted in the Greek text, the user
+% can use either one of the following solutions:
+% \begin{quote}
+%    1) \verb+>'a|+ \\
+%    2) \verb+\>'a|+
+% \end{quote}
+% Solution 1) saves hitting one key but breaks the kerning mechanism;
+% Solution 2) requires hitting one more key but preserves the kerning
+% mechanism.
+%
+% Only the diacritics that involve the breve (\u) and the macron (\=)
+% are regular TeX accent macros and behave as ordinary OT1-like
+% accents. There is no addressing of the marked glyphs, because the 256
+% font table can't accommodate so many glyphs.
+%
+% This file should be usable by inputting it even without requiring the
+% polutoniko language attribute of the Greek language.
+%
+% For more details read the teubner.pdf and the teubner-doc.pdf files
+% that are part of the teubner package documentation.

+% \subsection{Second set of extended accent definitions}
+% Now come another bunch of Milde's macros for composite glyphs; none of them
+% involves glyphs containing the subscript or adscript iota; this symbol, in facts
+% is postfixed to the previous glyph macro description, so its ligature takes place
+% after the previous glyph macro has been expanded; remember also that with the
+% ``high accents'' you can use both input strings, for example: |>'| and |\>'|;
+% therefore you can use the simple ligature input and, if kerning is not working
+% well with certain glyphs, you can just add a backslash in front of the ligature
+% sequence and everything gets fixed with proper ligatures. So, if |a>'u| with
+% certain fonts results in broken kerning, you just change it to |a\>'u| and the
+% kerning gets fixed.

+% With capital letters the dialytika (diaeresis) is maintained on top of the letters
+% `I' and `U', while for the other capital letters the diacritics are typeset in
+% front of them, not on top of them, as it is customary with Greek typesetting best
+% practice; the Unicode capital accented glyphs do exist, but they should never be
+% used; the CB fonts don't even contain them. There is no concern with kerning
+% because the diacritics preceding the capital letters are not preceded by something
+% else; what follows is kerned the usual way. With \"I and \"U specific kernings are
+% provided, if the dialytika macro |\"| is used, while kerning dith the dialytika
+% ligature temporarily work with kludges that should not be present in any font, but
+% the CB fonts have because the |AU| and |A'U| kerning was terrible without them;
+% now, with Milde's macros and or the pre-existing |\Id| and |\Ud| macros, should
+% not be of any concern.
