+\author{Günter Milde}
+\maketitle
+
+\noindent The file \href{tuenc-greek.def.html}{tuenc-greek.def} provides
+support for Greek \hyperref[licr]{LICR} macros and upcasing of text with
+XeTeX and LuaTeX. It is automatically loaded by the
+\href{textalpha-doc.pdf}{\emph{textalpha}} and
+\href{alphabeta-doc.pdf}{\emph{alphabeta}} packages as well as
+\href{http://www.ctan.org/pkg/babel-greek}{\emph{babel-greek}} when used
+with Unicode fonts (LuaTeX or XeTeX with
+\href{http://www.ctan.org/pkg/fontspec}{\emph{fontspec}}).
+
+\tableofcontents
+
+\section{Requirements}
+
+\subsection{fontspec}
+ The \href{http://www.ctan.org/pkg/fontspec}{\emph{fontspec}} package sets
+ up the TU Unicode font encoding for XeTeX and LuaTeX. However, it does
+ not provide Greek character names (\hyperref[licr]{LICR} macros).
+
+\subsection{suitable Unicode fonts}
+With the XeTeX or LuaTeX engines, the user must ensure that the selected
+font contains Greek glyphs (the default Latin Modern fonts have only capital
+Greek letters).
+There are no errors for missing glyphs, just warnings in the log file (but
+not the console output) and empty spaces in the output document.
+
+Examples for suitable fonts are given in the
+\href{http://mirrors.ctan.org/language/greek/greek-fontenc/README.html#TU}
+{greek-fontenc README}.
+
+
+\section{Usage}
+
+\texttt{tuenc-greek.def} is usually not loaded directly, but by one of
+\href{textalpha-doc.pdf}{\emph{textalpha}},
+\href{alphabeta-doc.pdf}{\emph{alphabeta}}, or \emph{Babel} (with the
+language option \href{http://www.ctan.org/pkg/babel-greek}{greek}). If these
+packages are loaded after
+\href{http://www.ctan.org/pkg/fontspec}{\emph{fontspec}}, Unicode font setup
+is amended for use of the Greek script.
+
+\section{LICR input%
+ \label{licr}}
+
+The LaTeX internal character representation (LICR) is a verbose,
+fail-safe 7-bit ASCII encoding that can be used unaltered under both, 8-bit
+TeX and XeTeX/LuaTeX. Use cases are macro definitions and generated text.
+
+See the source of this document,
+\href{tuenc-greek-doc.tex}{\texttt{tuenc-greek-doc.tex}} for the input used
+in the examples below.
+
+\subsection{Greek alphabet}
+
+Greek letters via LICR macros:
+\begin{quote}
+ \textAlpha{} \textBeta{} \textGamma{} \textDelta{} \textEpsilon{}
+ \textZeta{} \textEta{} \textTheta{} \textIota{} \textKappa{}
+ \textLambda{} \textMu{} \textNu{} \textXi{} \textOmicron{} \textPi{}
+ \textRho{} \textSigma{} \textTau{} \textUpsilon{} \textPhi{}
+ \textChi{} \textPsi{} \textOmega{}
+
+ \textalpha{} \textbeta{} \textgamma{} \textdelta{} \textepsilon{}
+ \textzeta{} \texteta{} \texttheta{} \textiota{} \textkappa{}
+ \textlambda{} \textmu{} \textnu{} \textxi{} \textomicron{} \textpi{}
+ \textrho{} \textsigma{} \texttau{} \textupsilon{}
+ \textphi{} \textchi{} \textpsi{} \textomega{}
+\end{quote}
+The small sigma is set with a different
+glyph if it ends a word:
+\begin{quote}
+ \textsigma{} \verb|textsigma|\\
+ \textfinalsigma{} \verb|textfinalsigma| or \verb|textvarsigma|
+\end{quote}
+The \verb|\textautosigma| macro, which automatically chooses the
+glyph according to the position, is not implemented for Unicode fonts.
+
+\subsection{Diacritics}
+
+Greek diacritics can be input by named macro or symbol macro:
+\begin{quote}
+ \acctonos\textalpha \'\textalpha{} \acctonos x\'x
+ \accvaria\textalpha \`\textalpha{} \accvaria x\`x
+ \accdialytika\textiota \"\textiota{} \accdialytika x\"x
+ \accperispomeni\textalpha \~\textalpha{} \accperispomeni x\~x
+ \accpsili\textalpha \>\textalpha{} \accpsili x\>x
+ \accdasia\textalpha \<\textalpha{} \accdasia x\<x
+\end{quote}
+Up-to-date Xe/LuaTeX normalizes base letter and combining diacritics to the
+corresponding pre-composed character if such a mapping is defined in the
+Unicode standard:
+
+\begin{quote}
+ % άάὰὰϊϊᾶᾶἀἀἁἁ
+ \acctonos α \'α
+ \accvaria α \`α
+ \accdialytika ι \"ι
+ \accperispomeni α \~α
+ \accpsili α \>α
+ \accdasia α \<α
+\end{quote}
+
+
+\subsubsection{perispomeni vs. tilde}
+
+The Greek \emph{perispomeni} has the look of a tilde but the semantic
+of a circumflex accent.
+The ``named'' \verb|\accperispomeni| macro uses COMBINING GREEK PERISPOMENI,
+while the standard tilde-accent macro \verb|\~| uses the COMBINING TILDE
+which is not normalized to GREEK LETTER ... WITH PERISPOMENI
+characters.
+
+Composite definitions for \verb|\~| select the pre-composed character:
+
+\begin{quote}
+ \~α = ᾶ, \~η = ῆ, \~ι = ῖ, \~υ = ῦ, \~ω = ῶ
+\end{quote}
+
+
+\subsubsection{combined diacritics}
+
+Combined accents are defined using combining diacritical characters.
+
+\begin{quote}
+\accdialytikatonos\textiota{} \"'\textiota{} \"\'\textiota{}
+\accdialytikatonos x \"'x \"\'x
+\accdialytikavaria\textiota{} \"`\textiota{} \"\`\textiota{}
+\accdialytikavaria x \"`x \"\`x
+\accdialytikaperispomeni\textiota{} \~"\textiota{} \~\"\textiota{}
+\accdialytikaperispomeni x \~"x \~\"x
+
+\accdasiaoxia\textiota{} \<'\textiota{} \<\'\textiota{}
+\accdasiaoxia x \<'x \<\'x
+\accdasiavaria\textiota{} \<`\textiota{} \<\`\textiota{}
+\accdasiavaria x \<`x \<\`x
+\accdasiaperispomeni\textiota{} \~<\textiota{} \~\<\textiota{}
+\accdasiaperispomeni x \~<x \~\<x
+
+\accpsilioxia\textiota{} \>'\textiota{} \>\'\textiota{}
+\accpsilioxia x \>'x \>\'x
+\accpsilivaria\textiota{} \>`\textiota{} \>\`\textiota{}
+\accpsilivaria x \>`x \>\`x
+\accpsiliperispomeni\textiota{} \~>\textiota{} \~\>\textiota{}
+\accpsiliperispomeni x \~>x \~\>x
+\end{quote}
+Composite diacritics overlap when they are not normalized to a pre-composed
+character. However, this is not a major problem in normal use as
+pre-composed characters exist in Unicode for all letters that are
+used with diacritics in (ancient, polytonic or monotonoc) Greek.
+
+
+\subsubsection{sub-iota}
+
+The sub-iota (ypogegrammeni/prosgegrammeni) is input after the base letter.
+
+\begin{itemize}
+\item \verb|\prosgegrammeni| sets a spacing GREEK PROSGEGRAMMENI:
+ \textAlpha\prosgegrammeni{} K\prosgegrammeni{}.
+\item \verb|\ypogegrammeni| sets a COMBINING GREEK YPOGEGRAMMENI:
+ \textalpha\ypogegrammeni{} k\ypogegrammeni{}.
+
+A Greek capital letter followed by COMBINING GREEK YPOGEGRAMMENI is
+normalized to the corresponding Greek capital letter WITH [.. AND]
+PROSGEGRAMMENI, if a mapping exists in the Unicode standard:
+ \textAlpha\ypogegrammeni{} but
+ K\ypogegrammeni{}.
+\end{itemize}
+
+\textAlpha\ypogegrammeni \textAlpha\prosgegrammeni
+\MakeLowercase{\textAlpha\ypogegrammeni \textAlpha\prosgegrammeni}
+\MakeUppercase{\textAlpha\ypogegrammeni \textAlpha\prosgegrammeni}

+\end{quote}
+
+\subsubsection{symbol variants}
+
+Mathematical notation uses variant shapes of some Greek letters as
+additional symbols. The variations have no syntactic meaning in Greek text
+and text fonts may use the variant shapes in place of the “regular” ones as
+a stylistic choice.
+
+Unicode defines separate code points for the symbol variants. TeX supports
+some of the variant shape symbols in mathematical mode, but its concept of
+“standard” vs. “variant” symbols differs from the distinction between
+“GREEK LETTER ...” vs. “GREEK ... SYMBOL” in the Unicode standard (see
+Table \ref{tab:symbol-variants}).
+
+\begin{table}[tbp]
+ \centering
+ \begin{tabular}{cccc}
+ \hline
+ \multicolumn{2}{c}{TeX math} & \multicolumn{2}{c}{Unicode} \\

+ \hline
+ \end{tabular}
+ \caption{Greek symbol variants in TeX and Unicode}
+ \label{tab:symbol-variants}
+\end{table}
+
+\texttt{tuenc-greek.def} defines three TextCommands for each of these
+letters:
+\begin{quote}
+ \verb|\text<name>| selects the Unicode GREEK LETTER ... variant,
+
+ \verb|\text<name>symbol| selects the Unicode
+ GREEK ... SYMBOL variant,
+
+ \verb|\textvar<name>| selects the variant
+ shape according to TeX' mathematical mode
+\end{quote}
+See Table \ref{tab:symbol-variant-macros} for the full list. The
+\href{alphabeta-doc.pdf}{\emph{alphabeta}} package defines short macros that
+work in text and math mode.

+\end{table}
+
+\subsubsection{Ancient Greek Numbers}
+
+Ancient Greek Numbers are missing in most fonts (including Libertine and
+Deja Vu). The “FreeSerif” font works fine:
+\begin{quote}
+\textpentedeka % GREEK ACROPHONIC ATTIC FIFTY
+\textpentehekaton % GREEK ACROPHONIC ATTIC FIVE HUNDRED
+\textpenteqilioi % GREEK ACROPHONIC ATTIC FIVE THOUSAND
+\textpentemuria % GREEK ACROPHONIC ATTIC FIFTY THOUSAND
+\end{quote}
+If the LGR font encoding is loaded via «fontenc» in the document preamble,
+Ancient Greek Numbers (as well as any other character) from LGR encoded
+8-bit TeX fonts can be used after a font-encoding switch. babel-greek
+defines the \verb|\textgreek| command for this purpose.
+\providecommand*{\textgreek}[1]{\leavevmode{%
+ \fontfamily{cmr}\fontencoding{LGR}\selectfont#1}%
+}
+\begin{quote}
+\textgreek{
+\textpentedeka % GREEK ACROPHONIC ATTIC FIFTY
+\textpentehekaton % GREEK ACROPHONIC ATTIC FIVE HUNDRED
+\textpenteqilioi % GREEK ACROPHONIC ATTIC FIVE THOUSAND
+\textpentemuria % GREEK ACROPHONIC ATTIC FIFTY THOUSAND
+}
+\end{quote}
+
+\section{Latin transcription}
+
+The Latin transcription known from LGR encoded 8-bit fonts%
+\footnote{ See the \href{http://www.ctan.org/pkg/teubner}{teubner} package
+or the file usage.pdf from the
+\href{http://www.ctan.org/pkg/babel-greek}{\emph{babel-greek}} package for a
+description.}
+does not work with Unicode fonts.
+
+It is possible to set up LGR encoded fonts parallel to Unicode fonts (see
+the preamble of the source file \url{tuenc-greek-doc.tex} for an example).
+The \verb|\textgreek| macro can then be used for the input of Greek letters
+via the \emph{Latin transcription}, e.g. «logos» becomes «\textgreek{logos}»
+and «\verb|\>aupn\'ia|» becomes «\textgreek{\>aupn\'ia}».
+
+Mark that you cannot use Unicode input with LGR encoded fonts except when
+running in 8-bit compatibility mode.
+LICR macros work in both, Unicode font encoding and LGR: compare
+ \>\textIota\textalpha\textnu\textomicron\textupsilon\textalpha
+ \textrho\acctonos\textiota\textomicron\textupsilon{}
+(Unicode font set up via fontspec) vs.
+\textgreek{\>\textIota\textalpha\textnu\textomicron\textupsilon\textalpha
+ \textrho\acctonos\textiota\textomicron\textupsilon}
+(LGR-encoded 8-bit font set up via NFSS commands).
+
+
+\section{UPPERCASE and lowercase}
+
+Capital Greek letters have Greek diacritics (except the dialytika and
+sub-iota) to the left (instead of above) and drop them if text is set in
+UPPERCASE, e.g.
+\ensuregreek{μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}}.
+
+The uccode/lccode corrections (taken from Apostolos Syropoulos xgreek
+package) ensure dropping of accents with \verb|\MakeUppercase| for literal
+Unicode characters.
+
+@uclclist additions ensure that upcasing also drops Greek diacritics.
+However, when the tonos, varia, and perispomeni accents
+are input using the symbol macros (\verb|\' \` \~|), this does not work, as
+they cannot be distinguished from Latin acute, grave, and tilde accents.%
+\footnote{This might be fixed with \textbackslash accACUTE,
+ \textbackslash accGRAVE, and \textbackslash accTILDE definitions
+ with corresponding @uclclist entries and composite definitions.}
+If these accents should be dropped by MakeUppercase, they must be input as
+named macro:
+
+\begin{quote}
+\acctonos\textalpha \'\textalpha{} \acctonos a\'a
+\accvaria\textalpha \`\textalpha{} \accvaria a\`a
+$\mapsto$
+\MakeUppercase{
+\acctonos\textalpha \'\textalpha{} \acctonos a\'a
+\accvaria\textalpha \`\textalpha{} \accvaria a\`a
+}
+\end{quote}
+
+\subsubsection{hiatus}
+
+Tonos and dasia mark a \emph{hiatus} (break-up of a diphthong) if placed on
+the first vowel of a diphtong (άι, άυ, έι, ἄι, ἄυ, ἔι). A dialytika must be
+placed on the second vowel if they are dropped.
+
+The «hiatus» feature works with macro input:
+\begin{quote}
+ % from teubner: άυλος/ΑΫΛΟΣ
+ \acctonos\textalpha\textupsilon λος $\mapsto$
+ \MakeUppercase{\acctonos\textalpha\textupsilon λος},
+ \accpsilioxia\textalpha\textupsilon λος $\mapsto$
+ \MakeUppercase{\accpsilioxia\textalpha\textupsilon λος},
+
+ % from http://diacritics.typo.cz/index.php?id=69 μάινα -> ΜΑΪΝΑ
+ m\acctonos\textalpha\textiota να $\mapsto$
+ \MakeUppercase{m\acctonos\textalpha\textiota να},
+ % from http://de.wikipedia.org/wiki/Neugriechische_Orthographie#Das_Trema
+ % κέικ, ἀυπνία/αϋπνία
+ \textkappa\acctonos\textepsilon\textiota\textkappa $\mapsto$
+ \MakeUppercase{\textkappa\acctonos\textepsilon\textiota\textkappa},
+ \accpsili\textalpha\textupsilon πνία $\mapsto$
+ \MakeUppercase{\accpsili\textalpha\textupsilon πνία}.
+\end{quote}
+
+It does not work with Unicode literals:
+\begin{quote}
+ άι, άυ, έι, ἄι, ἄυ, ἔι $\mapsto$ \MakeUppercase{άι, άυ, έι, ἄι, ἄυ, ἔι}
+\end{quote}
+
+or accent-macro + Unicode literals (yet?):
+\begin{quote}
+ \acctonos αι, \acctonos αυ, \acctonos ει, \'>αι, \'>αυ, \'>ει
+ $\mapsto$
+ \MakeUppercase{\acctonos αι, \acctonos αυ, \acctonos ει, \'>αι, \'>αυ, \'>ει}
+\end{quote}
+
+\section{Character Tables}
+
+The following tables list the Greek Unicode characters. In the input, the
+LICR macro is followed by the corresponding literal Unicode character.
