+\title{Test the Greek support for Babel}
+\author{Günter Milde}
+\date{2020/11/10}
+\maketitle
+
+The babel option ``greek'' activates the support for the Greek language
+defined in the file \texttt{greek.ldf} (source \texttt{greek.dtx}).
+
+\section{Language Switch}
+
+The declaration \verb|\selectlanguage| switches between languages.
+
+\begin{quote}
+  \selectlanguage{greek}
+  Τί φήις; Ἱδὼν ἐνθέδε παῖδ’ ἐλευθέραν
+  τὰς πλησίον Νύμφας στεφανοῦσαν, Σώστρατε,
+  ἐρῶν άπῆλθες εὐθύς;
+\end{quote}
+
+The macro \verb|\foreignlanguage| sets its second argument in the specified
+language. This is intended for short text parts or single words like
+\foreignlanguage{greek}{Βιβλιοθήκη}.
+
+There should be no inserted space before or after the language switch (may
+happen if there are unescaped linebreaks in the font or language definitions):
+
+\begin{quote}
+  Change script with \verb|ensuregreek|: |\ensuregreek{do\~ulos}|. Change
+  language with \verb|\foreignlanguage|: |\foreignlanguage{greek}{do\~ulos}|.
+\end{quote}
+
+\section{Font Encoding}
+
+In Greek text parts, the font encoding is automatically set to LGR if an
+8-bit TeX engine is used. (See \url{test-unicode-greek.tex} for usage of
+babel-greek with XeTeX or LuaTeX.)
+
+LGR has Greek characters in the slots reserved in a TeX \emph{standard text
+font encoding}. This means you need an explicit font encoding change for
+every Latin letter and some other symbols if the current font encoding is
+LGR.
+
+Babel defines the declaration \verb|\latintext| and the command
+\verb|\textlatin| to switch to the T1 or OT1 font encoding or typeset the
+argument using this encoding.
+
+Switching to a font encoding supporting the Greek script is possible without
+switching the Babel language using the declarations \verb|\greekscript| (no
+switch if the current encoding supports Greek script (e.g. the Unicode font
+encoding TU)) or \verb|\greektext| (always switch to LGR) and the
+corresponding macros \verb|\ensuregreek| or \verb|\textgreek|. These
+commands do not start a new paragraph:
+
+\greekscript Φίλων τοῦ \textlatin{TeX} (ΕΦΤ) --
+\latintext Friends (\ensuregreek{F\'ilwn}) of TeX.
+
+\texttt{greek.ldf} has some workarounds, so that macros relying on Latin
+characters in standard positions keep working. We test, that these
+definitions do not overwrite the selection of pre-composed characters for
+``copyright'' and ``registered trade mark'' by \emph{textcomp} (try copy and
+paste from the PDF output):
+
+Latin: A \& O, © ® ™ \\
+Greek (LGR): \ensuregreek{Α \& Ω, © ® ™}
+or input as macro \ensuregreek{\textAlpha{} \textampersand{} \textOmega{},
+\textcopyright{} \textregistered{} \texttrademark{}}.
+
+The ampersand should also work in mathematical mode: $ 1 \& 2 $
+
+To prevent Roman numerals being typeset in Greek letters we need to adopt
+the internal LaTeX commands. Note that this may cause errors when roman
+numerals are used in a situation where the macros need to be expanded:
+
+\makeatletter
+Latin:
+\@roman{1}, \@roman{2}, \@roman{3}, \@roman{4}, \ldots, \@roman{1975}
+\@Roman{1}, \@Roman{2}, \@Roman{3}, \@Roman{4}, \ldots, \@Roman{1975}
+
+Greek: \ensuregreek{
+\@roman{1}, \@roman{2}, \@roman{3}, \@roman{4}, \ldots, \@roman{1975}
+\@Roman{1}, \@Roman{2}, \@Roman{3}, \@Roman{4}, \ldots, \@Roman{1975}
+}
+\makeatother
+
+\section{MakeUppercase, MakeLowercase}
+
+Capital Greek letters have diacritics (except the dialytika and sub-iota) to
+the left (instead of above) and drop them in uppercase, e.g.
+\ensuregreek{μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}}.
+
+Upcased letters with diacritics keep the dialytika. This is implemented for
+all input variants of diacritics with dialytika. (\texttt{greek.ldf} has
+\emph{composite command} definitions to ensure this also works for accent
+characters "upcased" to the charcter No 159.)
+
+\foreignlanguage{greek}{\"i \"'i \"`i \"~i \'"i \`"i \~"i
+			\"u \"\'u \"\`u \"\~u
+			ϊ ΐ ῒ ῗ ΐ ῒ ῗ ϋ ΰ ῢ ῧ
+  $\mapsto$ \MakeUppercase{\"i \"'i \"`i \"~i \'"i \`"i \~"i
+    	    		   \"u \"\'u \"\`u \"\~u
+			   ϊ ΐ ῒ ῗ ΐ ῒ ῗ ϋ ΰ ῢ ῧ
+			   }
+}
+
+
+Tonos and dasia mark a \emph{hiatus} (break-up of a diphthong) if
+placed on the first vowel of a diphthong
+(\ensuregreek{\'ai, \'au, \'ei, \'>ai, \'>au, \'>ei}).
+A dialytika must be placed on the second vowel if they are dropped:
+(\ensuregreek{\MakeUppercase{\'ai, \'au, \'ei,  \'>ai, \'>au, \'>ei}}).
+
+\selectlanguage{greek}
+% from teubner: άυλος/ΑΫΛΟΣ

+k\'eik, $\mapsto$ \MakeUppercase{k\'eik}
+\accpsili{a}upn\'ia $\mapsto$ \MakeUppercase{\accpsili{a}upn\'ia}
+\selectlanguage{english}
+
+There are several alternative styles for the capitalized sub-iota.
+
+In order to let the Up/Downcasing work also with the Latin transcription
+defined by the LGR font encoding, ``babel-greek'' also defines lc/uccodes
+for non-standard assignments:
+
+\selectlanguage{greek}
+', ", `, >, <, | $\mapsto$ \MakeUppercase{', ", `, >, <, |}
+\selectlanguage{english}
+
+The uppercase of the zero-width space at the place of ``v'' is kept to point
+to the glyph at the position of ``V'', the Dasia-Oxia accent
+(\ensuregreek{\MakeUppercase{v}}):
+
+\begin{quotation}
+  greek-1.3i 2000/10/02: uc code of `v' is switched to V
+  so that mixed text appears correctly in headers.
+\end{quotation}
+
+Use \verb+\textcompwordmark+:
+not \foreignlanguage{greek}{avu $\mapsto$ \MakeUppercase{avu}} but
+\foreignlanguage{greek}{a\textcompwordmark u
+$\mapsto$ \MakeUppercase{a\textcompwordmark u}}
+
+The following subsections test MakeUppercase and MakeLowercase with all
+characters defined in lgrenc.dfu:
+
+\subsection{Greek and Coptic}

+\end{quote}
+\end{document}
+
+Letters and sub-iota upcased, other diacritics except dialytika dropped.
+
+There is no capital Koppa in LGR, therefore \ensuregreek{ϟ} is left
+unchanged with MakeUppercase.
+
+
+MakeLowercase:
+
+\begin{quote}
+  \MakeLowercase{\GreekAndCoptic}\\
+  \MakeLowercase{\greekandcoptic}
+\end{quote}
+
+The lowercase of \ensuregreek{Σ} is the «auto-sigma» (\verb+\textautosigma+):
+\ensuregreek{ΣΣ $\mapsto$ \MakeLowercase{ΣΣ}}. Add a ZWNJ or use the
+\verb+\noboundary+ macro to prevent conversion to final sigma:
+\ensuregreek{\MakeLowercase{ΣΣ‌}}. The lowercase of GREEK LETTER STIGMA
+\ensuregreek{Ϛ} is \ensuregreek{\MakeLowercase{Ϛ}} not \verb|\textvarstigma|
+(\ensuregreek\textvarstigma).

+\section{Babel Strings}
+
+Babel defines macros for several autogenerated strings so that they may
+appear in the choosen language. babel-greek uses LICRs in order to let the

 \section{Font Encoding}
 
-In Greek text parts, the font encoding is automatically set to LGR if an
-8-bit TeX engine is used. (See \url{test-unicode-greek.tex} for usage of
-babel-greek with XeTeX or LuaTeX.)
-
-LGR has Greek characters in the slots reserved in a TeX \emph{standard text
-font encoding}. This means you need an explicit font encoding change for
-every Latin letter and some other symbols if the current font encoding is
-LGR.
-
-The Babel core defines the declaration \verb|\latintext| and the command
-\verb|\textlatin| to switch to the T1 or OT1 font encoding or typeset the
-argument using this encoding.
-
-Switching to a font encoding supporting the Greek script is possible without
-switching the Babel language using the declarations \verb|\greekscript| (no
-switch if the current encoding supports Greek script (e.g. the Unicode font
-encoding TU)) or \verb|\greektext| (always switch to LGR) and the
-corresponding macros \verb|\ensuregreek| or \verb|\textgreek|. These
-commands do not start a new paragraph:
-
-\greekscript Φίλων τοῦ \textlatin{TeX} (ΕΦΤ) --
-\latintext Friends (\ensuregreek{F\'ilwn}) of TeX.
-
-\texttt{greek.ldf} has some workarounds, so that macros relying on Latin
-characters in standard positions keep working. We test, that these
-definitions do not overwrite the selection of pre-composed characters for
-``copyright'' and ``registered trade mark'' by \emph{textcomp} (try copy and
-paste from the PDF output):
-
-Latin: A \& O, © ® ™ \\
-Greek (LGR): \ensuregreek{Α \textampersand{} Ω,
-\textcopyright{} \textregistered{} \texttrademark{}, \& © ® ™ }.
-
-The ampersand should also work in mathematical mode: $ 1 \& 2 $
-
-To prevent Roman numerals being typeset in Greek letters we need to adopt
-the internal LaTeX commands. Note that this may cause errors when roman
-numerals are used in a situation where the macros need to be expanded:
-
-\makeatletter
-Latin:
-\@roman{1}, \@roman{2}, \@roman{3}, \@roman{4}, \ldots, \@roman{1975}
-\@Roman{1}, \@Roman{2}, \@Roman{3}, \@Roman{4}, \ldots, \@Roman{1975}

-Capital Greek letters have diacritics (except the dialytika and sub-iota) to
-the left (instead of above) and drop them in uppercase, e.g.
-\ensuregreek{μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}}.
-
-Upcased letters with diacritics keep the dialytika. This is implemented for
-all input variants of diacritics with dialytika. (\texttt{greek.ldf} has
-\emph{composite command} definitions to ensure this also works for accent
-characters "upcased" to the charcter No 159.)

-\title{Greek support for Babel with XeTeX/LuaTeX}
-\author{Günter Milde}
-\date{2016/09/07}
-\maketitle
-
-The babel option «greek» activates the support for the Greek language
-defined in the file «greek.ldf» (source «greek.dtx»).
-
-Typesetting Greek texts requires a font containing Greek letters. With the
-XeTeX or LuaTeX engines, the user must ensure that the selected font
-contains the required glyphs (the default Latin Modern fonts miss most of
-them). Examples for suitable fonts are the «Deja Vu», «Linux Libertine»,
-or «Free Serif» OpenType fonts.
-
-\section{Language Switch}
-
-The declaration \verb|\selectlanguage| switches between languages.
-
-\begin{quote}
-  \selectlanguage{greek}
-  Τί φήις; Ἱδὼν ἐνθέδε παῖδ’ ἐλευθέραν
-  τὰς πλησίον Νύμφας στεφανοῦσαν, Σώστρατε,
-  ἐρῶν άπῆλθες εὐθύς;
-\end{quote}
-
-The command \verb|\foreignlanguage| sets its second argument in the language
-specified as first argument. This is intended for short text parts like
-\foreignlanguage{greek}{Βιβλιοθήκη}.
-
-\section{Font Encoding}
-
-Every language switch to \texttt{greek} calls the \verb|\extrasgreek|
-command which in turn calls \verb|\greekscript| to ensure a Greek-supporting
-font encoding (LGR, TU, EU1, or EU2). Under Xe/LuaTeX the font encoding
-normally just remains Unicode (TU). For customization, you can add to or
-redefine the \verb|\extrasgreek| command.
-
-The LGR font encoding does not support Latin characters. Therefore, the
-Babel core defines the declaration \verb|\latintext| and the command
-\verb|\textlatin| to switch to the TU, EU1, EU2, T1 or OT1 font encoding or
-typeset the argument using this encoding. At this point, the «latinencoding»
-is \latinencoding.
-
-Every language switch from \texttt{greek} calls the \verb|\noextrasgreek|
-command which in turn calls \verb|\latintext|.\\
-For customization, you can
-add to or redefine the \verb|\noextrasgreek| command.
-
-With the Unicode font encoding TU, EU1, or EU2,
-Latin characters can be used in Greek text parts and
-input via the «LGR Latin transcription» is not possible.%
-\footnote{%
-  The \emph{xunicode} package provides with the \texttt{tipa} emulation an
-  example how this could be achieved also for Unicode fonts. Alternatively,
-  LGR encoded fonts can be used (see test-unicode-lgr.tex).

-definitions for the Unicode font encoding (TU, EU1 or EU2) from the file
-\texttt{greek-euenc.def} provided with
-\href{http://www.ctan.org/pkg/greek-fontenc}{greek-fontenc} since
-version~0.10.
-
-With this setup, it is also possible to use accent macros instead of
-pre-composed Unicode characters for letters with diacritics:
-«Τ\'ι φ\'ηις;», «\`<ορα = \accdasiavaria{ο}ρα».

-\section{Greek Numerals}

-See greek.pdf for the formation rules of Greek numerals.
-Some examples:
-
-\selectlanguage{greek}
-
-\greeknumeral{1},
-\greeknumeral{2},
-\greeknumeral{3},
-\greeknumeral{4},
-\greeknumeral{5},
-\greeknumeral{6},

-\greeknumeral{8},
-\greeknumeral{9},
-\greeknumeral{10},
-\greeknumeral{11},
-\greeknumeral{12},
-\greeknumeral{20},
-\greeknumeral{345},
-\greeknumeral{500},
-\greeknumeral{1997},
-\greeknumeral{2013},
-
-\Greeknumeral{1},
-\Greeknumeral{2},
-\Greeknumeral{3},
-\Greeknumeral{4},
-\Greeknumeral{5},
-\Greeknumeral{6},
-\Greeknumeral{7},
-\Greeknumeral{8},
-\Greeknumeral{9},
-\Greeknumeral{10},
-\Greeknumeral{11},
-\Greeknumeral{12},
-\Greeknumeral{20},
-\Greeknumeral{345},
-\Greeknumeral{500},
-\Greeknumeral{1997},
-\Greeknumeral{2013},
-
-
-Enumerated lists use Greek characters/numerals in the second and fourth level:
-
-\selectlanguage{greek}
-\begin{enumerate}
-  \item item 1
-  \begin{enumerate}
-    \item item 1.1
-    \begin{enumerate}
-      \item item 1.1.1
-       \begin{enumerate}
-         \item item 1.1.1.1
-         \item item 1.1.1.2
-       \end{enumerate}
-      \item item 1.1.2
-    \end{enumerate}
-  \end{enumerate}
-\end{enumerate}
-\selectlanguage{english}
-
-
-This may be problematic with fonts that only partially support Greek and
-miss the numeral signs (dexiakeraia and aristerikeraia).
-
-You may redefine the commands \verb+\textdexiakeraia+ and
-\verb+\textaristerikeraia+ to some substitute characters.
-Or, if you prefer the ``normal'' enumeration, write in the preamble after
-loading babel:
-
-\begin{verbatim}
-  \makeatletter
-  \addto\extrasgreek{\let\@alph\latin@alph
-  		     \let\@Alph\latin@Alph}
-  \makeatother
-\end{verbatim}
-
-
