+Mathematical notation distinguishes variant shapes for beta (β|ϐ), theta
+(θ|ϑ), phi (φ|ϕ), pi (π|ϖ), kappa (κ|ϰ), rho (ρ|ϱ), Theta (Θ|ϴ), and epsilon
+(ε|ϵ).  The variations have no syntactic meaning in Greek text and Greek
+text fonts use the shape variants indiscriminately.
+
+Unicode defines separate code points for the symbol variants for use in
+mathematical context. However, they are sometimes also used in place of the
+corresponding letter characters in Unicode-encoded text.
+
+The variant shapes are not given separate code-points in the LGR_ font
+encoding.
+
+In mathematical mode, TeX supports the distinction between θ|ϑ, π|ϖ, φ|ϕ,
+ρ|ϱ, and ε|ϵ with ``\var<lettername>`` macros. However, the mapping of
+letter/symbol in Unicode to "normal"/variant in TeX is inconsistent
+and variant macros for ϴ ϐ, and ϰ are not available without additional
+packages (e.g. amssymb_ provides ϰ as ``\varkappa``).
+
+`greek-fontenc` provides ``\text<lettername>symbol`` LICR macros for these
+characters:
+
+* With Unicode fonts, the macros select the GREEK
+  <lettername> SYMBOL``.
+
+* With LGR encoded fonts, they report an error by default and are mapped to

+
+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

+“standard” vs. “variant” symbols differs from the distinction between
+“GREEK LETTER ...” vs. “GREEK ... SYMBOL” in the Unicode standard

 <h1>Motivation</h1>
-<p>By default, the <tt class="literal">\alpha, \beta, ...</tt> macros for Greek letters
+<p>By default, the <span class="docutils literal">\alpha, \beta, ...</span> macros for Greek letters
 are only valid in mathematical mode.</p>
 <p>With this package, the math macros are redefined to work in both, text and
 math mode, so that Greek letters can be specified with the established
 command names in text, too.</p>
-<p>If used together with the <tt class="literal">utf8</tt> option of <a class="reference external" href="http://www.ctan.org/pkg/inputenc">inputenc</a>, literal Unicode

 characters can be used for Greek symbols in mathematical formulas.</p>

+<div class="admonition attention">
 <p class="admonition-title">Attention!</p>
 <p>The macros work well in any font encoding for single symbols.
 However, with 8-bit TeX, the automatic font-encoding switches behind the
 doors interfere with kerning between letters and replacement of
 accent+character with a pre-composed character.</p>
 <p>Therefore, Greek text should be written with the help of <a class="reference external" href="http://www.ctan.org/cgi-bin/ctanPackageInformation.py?id=babel">babel</a> or

+The LaTeX internal character representation (LICR) is a verbose but
+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{greek-euenc-doc.tex}{\texttt{greek-euenc-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{}       textsigma\\
+  \textfinalsigma{}  textfinalsigma or textvarsigma
+\end{quote}
+The \verb|\textautosigma| macro/feature, which automatically chooses the
+glyph according to the position, is not implemented for Unicode fonts.
 
-\textAlpha{} \textBeta{} \textGamma{} \textDelta{} \textEpsilon{}
-\textZeta{} \textEta{} \textTheta{} \textIota{} \textKappa{}
-\textLambda{} \textMu{} \textNu{} \textXi{} \textOmicron{} \textPi{}
-\textRho{} \textSigma{} \textTau{} \textUpsilon{} \textPhi{}
-\textChi{} \textPsi{} \textOmega{}
+\subsection{Diacritics}
 
-\textalpha{} \textbeta{} \textgamma{} \textdelta{} \textepsilon{}
-\textzeta{} \texteta{} \texttheta{} \textiota{} \textkappa{}
-\textlambda{} \textmu{} \textnu{} \textxi{} \textomicron{} \textpi{}
-\textrho{} \textsigma{} \texttau{} \textupsilon{}
-\textphi{} \textchi{} \textpsi{} \textomega{}
+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 XeTeX/LuaTeX (or fontspec?) normalizes base letter and
+combining diacritics to the corresponding pre-composed character if such a
+mapping is defined in the Unicode standard:
 
-The small sigma is set with a different
-glyph if it ends a word:
+\begin{quote}
+  \acctonos α       \'α
+  \accvaria α       \`α
+  \accdialytika ι   \"ι
+  \accperispomeni α \~α
+  \accpsili α       \>α
+  \accdasia α       \<α
+\end{quote}
 
-\begin{itemize}
-  \item[\textsigma]       textsigma
-  \item[\textfinalsigma]  textfinalsigma or textvarsigma
-\end{itemize}
 
-In the Latin transcription defined by the 8-bit LGR font encoding, the
-letter `s' stands for \verb|\textautosigma| which automatically chooses the
-glyph according to the position. This macro/feature is not implemented for
-Unicode fonts.
+\subsubsection{perispomeni vs. tilde}
 
-\subsection{Additional Greek symbols}
+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

+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

+\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{%

+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.
+
+Is is possible to set up LGR encoded fonts parallel to Unicode fonts (see
+the preamble of the source file \url{greek-euenc-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

+
+
+\section{UPPERCASE and lowercase}
 
-However, when the tonos, varia, and perispomeni accents are input using the
-symbol macros (\verb|\' \` \~|), they behave like standard accents with
-XeTeX/LuaTeX. If these accents should be dropped by MakeUppercase, they must
-be input as named macro:
+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       x\'x

-\accperispomeni\textalpha \~\textalpha{}  \accperispomeni x\~x
+\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},

+  \accpsili\textalpha\textupsilon πνία $\mapsto$
+  \MakeUppercase{\accpsili\textalpha\textupsilon πνία}.
+\end{quote}
+
+It does not work (yet?) with Unicode literals:
+\begin{quote}
+  άι, άυ, έι, ἄι, ἄυ, ἔι $\mapsto$ \MakeUppercase{άι, άυ, έι, ἄι, ἄυ, ἔι}
+\end{quote}
+
+\section{Character Tables}
 
-The sub-iota is input after the base letter.
-Ligature definitions in the 8-bit LGR fonts ensure that precomposed
-characters are used. This does not work with Unicode fonts:\footnote{%
-  When copy/pasting generated output from the “evince” PDF
-  viewer, the COMBINING GREEK YPOGEGRAMMENI is merged with the base
-  character. A capital letter + combining ypogegrammeni results in GREEK
-  CAPITAL LETTER ... WITH [.. AND] PROSGEGRAMMENI). This indicates that
-  the combining \emph{ypogegrammeni} should also be used together with
-  capital base letters.}
-
-\textalpha\ypogegrammeni{} x\ypogegrammeni{}
-\textAlpha\prosgegrammeni{} X\prosgegrammeni,
-\textAlpha\ypogegrammeni{} X\ypogegrammeni,
-see also the \emph{Greek extended} Unicode block below.
-
-Both, the standard LaTeX and the “xunicode” composite mechanism require
-the first part of a composite definition to be a macro requiring one
-argument.  I.e. selecting pre-defined characters with sub-iota would require
-prefix \verb|\accypogegrammeni| and \verb|\accprosgegrammeni| accent
-macros and composite definitions for all combination of letters and letters
-with diacritic and sub-iota.
+The following tables list the Greek Unicode characters. In the input, the
+LICR macro is followed by the corresponding literal Unicode character.
 
 \subsection{Greek and Coptic Unicode block}
 
-Greek symbols from the Greek and Coptic Unicode block are fully supported:

+LuaTeX and XeTeX, it provides a compatible interface for Greek in text mode.</p>
+<p>See the source of this document url{textalpha-doc.tex} for a setup and
+usage example, the literate source of the package

+emph{Font setup for Greek with XeTeX/LuaTeX}.</p>
+<p>subsection{option texttt{normalize-symbols}}</p>
+<p>Mathematical notation uses variant shapes of some Greek letters as
+additional symbols.  There are separate code points for the symbol variants
+in Unicode but not in the LGR font encoding used for Greek in 8-bit TeX.
+TeX supports some of the variant shape symbols in mathematical mode
+($theta|vartheta, phi|varphi, pi|varpi, rho|varrho,
+epsilon|varepsilon$).</p>
+<p>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.
+However, some Greek texts in Unicode encoding use these GREEK
+… SYMBOL characters in place of the corresponding GREEK LETTER …
+characters.</p>
+<p>The texttt{normalize-symbols} option merges letters and symbols to Greek
+letters. This way, text copied from external sources can be compiled without
+errors even if it contains GREEK SYMBOL characters in place of GREEK LETTERS:

 \maketitle
 
+Standard 8-bit TeX fonts do not support the Greek script. If Greek
+characters shall be used with 8-bit TeX, setup of a Greek text font and an
+explcit font-encoding switch is required.
+
 With the \emph{textalpha} package, you can easily write a single Greek
 symbol (like \textPsi{} or \textmu{}) or a
 \textlambda\textomicron\textgamma\textomicron\textvarsigma{} in non-Greek
 text as well as ISO-conforming formulas with upright constants (like
 \textpi): $A = \mbox{\textpi} r^2$ vs. $A = \pi r^2$. Input is possible via
-LICR macros (\verb|\textalpha| \ldots \verb|\textOmega|) or (with
-\emph{\href{http://www.ctan.org/pkg/greek-inputenc}{greek-inputenc}} and the
-utf8 option or XeTeX/LuaTeX) Unicode literals.
+LICR macros (\verb|\textalpha| \ldots \verb|\textOmega|)

+
+\section{Usage}
+
+Load this package in the preamble of your document with
+\begin{verbatim}
+  \usepackage{textalpha}
+\end{verbatim}
+If it is loaded after the setup of Unicode fonts with
+\href{http://www.ctan.org/pkg/fontspec}{\emph{fontspec}} package under
+LuaTeX and XeTeX, it provides a compatible interface for Greek in text mode.
+
+If you want to merge symbol variants, use the
+\texttt{normalize-symbols} option:%
+\footnote{This option is ignored with Unicode fonts.}
+\begin{verbatim}
+  \usepackage[normalize-symbols]{textalpha}
+\end{verbatim}
 
 See the source of this document \url{textalpha-doc.tex} for a setup and
-usage example and the literate source of the package

+usage example, the literate source of the package
+\href{textalpha.sty.html}{textalpha.sty} for the implementation, and
+\emph{Font setup for Greek with XeTeX/LuaTeX}
+(\href{euenc-doc.pdf}{euenc-doc.pdf}) for special feature under XeTeX/LuaTeX.
+
+
+\subsection{option \texttt{normalize-symbols}}
+
+This option is ignored with Unicode fonts.
+
+Mathematical notation uses variant shapes of some Greek letters as
+additional symbols.  There are separate code points for the symbol variants
+in Unicode but not in the LGR font encoding used for Greek in 8-bit TeX.
+TeX supports some of the variant shape symbols in mathematical mode
+($\theta|\vartheta, \phi|\varphi, \pi|\varpi, \rho|\varrho,
+\epsilon|\varepsilon$).
+
+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.
+However, some Greek texts in Unicode encoding use these GREEK
+... SYMBOL characters in place of the corresponding GREEK LETTER ...
+characters.
+
+The \texttt{normalize-symbols} option merges letters and symbols to Greek
+letters. This way, text copied from external sources can be compiled without
+errors even if it contains GREEK SYMBOL characters in place of GREEK LETTERS:
+\begin{quote}
+  This text uses both variants for beta (β|ϐ), theta (θ|ϑ), phi (φ|ϕ), pi
+  (π|ϖ), kappa (κ|ϰ), rho (ρ|ϱ), Theta (Θ|ϴ), and epsilon (ε|ϵ) in the LaTeX
+  source.
+\end{quote}
+
+\textbf{Attention}: Do not use this option in cases where the distinction
+between the symbol variants may be important (e.g. in a mathematical or
+scientific context). Try the \emph{alphabeta} package with the
+respective characters in math mode or use XeTeX/LuaTeX with Unicode fonts in
+these cases.
+
+\section{Limitations}
+
+Because the internal font encoding switch interferes with other work behind
+the scenes, kerning, diacritics and up/down-casing show problems if Greek
+letters are used without explicit change of the font encoding.
+
+These problems can be avoided by use of \emph{babel} and the correct
+language setting (greek), an explicit font encoding switch (e.g.
+wrapping the Greek text in \verb|\ensuregreek|%
+\footnote{The \texttt{\textbackslash ensuregreek} macro ensures the argument
+  is set in a font encoding supporting Greek.
+  % This can be used to fix these
+  % problems without adverse side-effects if the active font encoding is
+  % already LGR or Unicode.
+  },
+or XeTeX/LuaTeX with Unicode fonts.
+
+
+\subsection{Diacritics}
+
+Composition of diacritics (like \verb|\accdasia\acctonos| or \verb|\<\'|)
+fails in other font encodings. Long names (like \verb|\accdasiaoxia|) work.
+
+With LGR, pre-composed glyphs are chosen if available. In other font
+encodings, accent macros do not select pre-composed characters. (The
+difference is a sub-optimal placement of the accent and becomes obvious if
+you drag-and-drop text from the PDF version of this document.):
+
+\begin{quote}
+  \ensuregreek{\<'a \accdasia\acctonos a \accdasiaoxia a
+  \accdasiaoxia\textalpha} (LGR) vs. \accdasiaoxia\textalpha{} (T1).
+\end{quote}
+
+According to Greek typographical tradition, diacritics (except the
+dialytika) are placed before capital letters in Titlecase and dropped in
+UPPERCASE:
+%
+\begin{quote}
+  \ensuregreek{%
+    \<{\textalpha} \>{\textepsilon} \"'{\textiota} \`>\texteta{}
+    \'<{\textomicron} \~<{\textupsilon} \~>{\textomega}
+    \quad
+    \<{\textAlpha} \>{\textEpsilon} \"{\textIota} \`>\textEta{}
+    \'<{\textOmicron} \~<{\textUpsilon} \~>{\textOmega}
+    \quad
+    \MakeUppercase{%
+      \<{\textalpha} \>{\textepsilon} \"'{\textiota} \`\>\texteta{}
+      \'<{\textomicron} \~<{\textupsilon} \~>{\textomega}
+    }
+  }
+\end{quote}
+%
+This fails for accent macros if the active font encoding is not LGR or
+Unicode. Pre-composed literal Unicode characters are handled correctly:
+\begin{quote}
+  \ensuregreek{\'\textAlpha/Ά}  (LICR/Unicode in LGR) vs.
+  \'\textAlpha/Ά (LICR/Unicode in T1).
+\end{quote}
+
+The dialytika marks a \emph{hiatus} (break-up of a diphthong). It must be
+present in UPPERCASE even where it is redundant in lowercase (the hiatus can
+also be marked by an accent on the first character of a diphthong). The
+auto-hiatus feature works in LGR and Unicode font encodings only:
+\begin{quote}
+  \acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{} $\mapsto$
+  \MakeUppercase{\ensuregreek{
+    \acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{}
+  }} (LGR) vs.
+  \MakeUppercase{
+    \acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{}%
+  } (T1)
+\end{quote}
+
+Currently, the second vowel of the diphthong must be given as macro, not
+Unicode literal if the auto-hiatus feature should work:
+\begin{quote}
+\ensuregreek{ἀ\textupsilon{}πνία} $\mapsto$
+\ensuregreek{\MakeUppercase{\ensuregreek{ἀ\textupsilon{}πνία}}} (LGR) vs.
