-With the \emph{alphabeta} package, you can write Greek letters ``by name''

+The \emph{alphabeta} package makes the standard macros for Greek letters in

+
+The \emph{alphabeta} package depends on
+\emph{\href{textalpha-doc.pdf}{textalpha}} (both are part of
+\emph{\href{http://www.ctan.org/pkg/greek-fontenc}{greek-fontenc}}).
+It can be used under 8-bit TeX as well as XeTeX/LuaTeX (this document is
+typeset with \engine). Depending on the converter and fonts, different
+\hyperref[sec:limitations]{limitations} apply.
+
+The package conflicts with
+\href{http://www.ctan.org/pkg/unicode-math}{\emph{unicode-math}}.
+
+It also fails, if the \texttt{utf8x} input encoding is selected (interface
+to the \href{http://www.ctan.org/pkg/ucs}{\emph{ucs}} package using a
+non-compatible definition of \verb+\DeclareUnicodeCharacter+).
 
 \section{Usage}
 
 Load this package in the preamble of your document (after font and math
 setup) with
 \begin{verbatim}
-  \usepackage{alphabeta}
-\end{verbatim}
-or, if you want to merge symbol variants, with the
-\texttt{normalize-symbols} option:

-  \usepackage[normalize-symbols]{alphabeta}

-\subsection{option normalize-symbols}
 
-The \texttt{normalize-symbols} option is passed to the
-\href{alphabeta-doc.pdf}{\emph{alphabeta}} package. It
-merges ``letters'' and ``symbol`` variants of some Greek
-letters to the ``letter'' character (but is ignored with Unicode fonts):
-\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}
+\subsection{options}
 
+Package options are passed to the \href{alphabeta-doc.pdf}{\emph{alphabeta}}
+package. Example call with options:
+
+\begin{verbatim}
+      \usepackage[normalize-symbols,keep-semicolon]{alphabeta}
+\end{verbatim}
+
+\texttt{normalize-symbols} merges ``letters'' and ``symbol`` variants of
+some Greek letters to the ``letter'' character:
+\footnote{The normalize-symbols option was added in version 0.13 (2015-08-03).
+  Unicode input of the symbol variants requires at least version~1.6
+  (2015-08-05) of
+  \emph{\href{http://www.ctan.org/pkg/greek-inputenc}{greek-inputenc}}.}
+Without this option, the symbol variant characters cannot be used in text,
+because they are not supported by 8-bit Greek fonts (LGR encoding).
+The \texttt{normalize-symbols} option is ignored, if you compile the
+document with XeTeX or LuaTeX using Unicode fonts.
 \textbf{Attention}: Be careful in cases where the distinction between the
 symbol variants may be important (e.g. in a mathematical or scientific
 context). Use XeTeX/LuaTeX with Unicode fonts or the respective characters
-in math mode (e.g. $π$ vs. $ϖ$).
+in mathematical mode (e.g. $\pi$ vs. $\varpi$).
+
+The option \texttt{keep-semicolon} prevents conversion of the semicolon to
+an \emph{ano teleia} (see \emph{\href{textalpha-doc.pdf}{textalpha-doc}}).
+
+\subsection{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 \href{greek-euenc-doc.pdf}{greek-euenc-doc}.
+
+The \emph{alphabeta} package defines generic macros for these variants that
+are short forms of the set defined in \texttt{greek-euenc.def}:
+\begin{quote}
+  \verb|\<name>| selects the Unicode GREEK LETTER ... variant,
+
+  \verb|\<name>symbol| selects the Unicode
+     GREEK ... SYMBOL variant,
+
+  \verb|\var<name>| selects the variant
+    shape according to TeX' mathematical mode
+\end{quote}
+See Table \ref{tab:symbol-variant-macros} for the full list.
+
+\section{Limitations \label{sec:limitations}}
+
+With 8-bit TeX, the limitations described in the
+\href{textalpha-doc.pdf}{textalpha documentation} apply. See also the tests
+in section \hyperref[sec:8-bit-limitations]{8 bit limitations}.
+
+With XeTeX/LuaTeX and Unicode fonts, literal Unicode characters cannot be
+used in formulas (the log file reports missing characters)
+This is a generic TeX limitation which \emph{alphabeta} overcomes if used
+under 8-bit TeX. Under XeTeX/LuaTeX it may be lifted using the
+\href{http://www.ctan.org/pkg/unicode-math}{\emph{unicode-math}}
+package, but unfortunately, \emph{alphabeta} conflicts
+with \emph{unicode-math}.

 PDF strings do not know math mode. The content of a formula or equation is
 evaluated in text mode with non-valid commands discarded (and warnings
 written to the log). This works resonably well for simple formulas (but not,
 e.g., for super-/subscripts). With the \emph{alphabeta} package, it works
 also for Greek letters.

+  ====== ==========  ========================================================
+  0.1    2013-07-16  initial version
+  0.1.1  2013-07-18  bugfix: wrong breathings psilioxia -> dasiaoxia
+  0.1.2  2013-07-19  bugfix: Disable composite defs starting with char macro,
+         ..          fix "hiatus" handling.
+  0.1.3  2013-07-24  fix "input" path.
+  0.1.4  2013-10-01  remove clashing defs for legacy characters with oxia,

+  ====== ==========  ========================================================
+
+.. contents::
+
+Motivation
+==========
+
+LICR macro definitions for the Greek script are missing in both, xunicode_
+and euenc_.
+
+This file expands the font encoding definition files ``eu1enc.def`` rsp.
+``eu2enc.def`` from euenc_ defining `LaTeX Internal Character
+Representaction` (LICR) macros for Greek letters and symbols. It works
+independed of xunicode_ using the standard commands for `LaTeX2e font
+selection`_.
+
+Requirements
+============
+
+Requires XeTeX or LuaTeX, fontspec_, and a font with Greek characters.
+
+See `<greek-euenc-doc.tex>`_ and `<greek-euenc-doc.pdf>`_ for setup and
+usage examples.
+
+
+Greek Diacritics
+================
+
+Define "named macros" for simple and combined diacritics.
+
+* Named accent macros can be used instead of the ``\@tabacckludge`` by
+  to-LaTeX converters to ensure working also inside the tabbing environment.
+
+* Named macros are required for upcasing according to Greek typesetting
+  conventions and in the definition of composite commands.
+
+Greek alias names for standard accents::
+
+  \DeclareTextCommand{\acctonos}{\LastDeclaredEncoding}{\@tabacckludge'}
+  \DeclareTextCommand{\accvaria}{\LastDeclaredEncoding}{\@tabacckludge`}
+  \DeclareTextCommand{\accdialytika}{\LastDeclaredEncoding}{\@tabacckludge"}
+  
+The combining perispomeni character is normalized with Greek base letters,
+while the (standard) combining tilde is not::
+
+  \DeclareTextCommand{\accperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0342 }
+  
+Breathings:
+
+(The COMBINING GREEK KORONIS is a legacy character, discarded in favour of
+COMBINING COMMA ABOVE) ::
+
+  \DeclareTextCommand{\accpsili}{\LastDeclaredEncoding}[1]{#1\char"0313 } % ψιλή spiritus lenis (smooth breathing)
+  \DeclareTextCommand{\accdasia}{\LastDeclaredEncoding}[1]{#1\char"0314 } % δασεῖα spiritus asper (rough breathing)
+  
+  
+Sub-iota:
+
+``\ypogegrammeni`` is a postfix accent (ligature in LGR) ::
+
+  \DeclareTextSymbol{\ypogegrammeni}{\LastDeclaredEncoding}{0837} % COMBINING GREEK YPOGEGRAMMENI
+  
+Combined diacritics::
+
+  % The COMBINING DIALYTIKA TONOS is discarded and not well supported by fonts:
+  \DeclareTextCommand{\accdialytikatonos}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0301 }
+  \DeclareTextCommand{\accdialytikavaria}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0300 }
+  \DeclareTextCommand{\accdialytikaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0342 \char"0308 }
+  
+  \DeclareTextCommand{\accdasiaoxia}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0301 }
+  \DeclareTextCommand{\accdasiavaria}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0300 }
+  \DeclareTextCommand{\accdasiaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0342 }
+  
+  \DeclareTextCommand{\accpsilioxia}{\LastDeclaredEncoding}[1]{#1\char"0301 \char"0313 }
+  \DeclareTextCommand{\accpsilivaria}{\LastDeclaredEncoding}[1]{#1\char"0300 \char"0313 }

+uclclist
+~~~~~~~~
+
+The common Greek font encoding definitions in greek-fontenc.def_ extend the
+`uclclist` with Greek LICR macros. Here, we add textkoppa/textKoppa and
+Unicode-specific "hiatus_" handling (copied from lgrenc.def_ and changed
+Latin transcription to Unicode literals).
+
+@uclclist extension (see also greek-fontenc.def_)::
+
+  \providecommand*\greek@euenc@update@uclclist{%
+    \expandafter\def\expandafter\@uclclist\expandafter{%
+      \@uclclist
+      \textkoppa \textKoppa
+    }%
+    \let\greek@euenc@update@uclclist\relax
+  }
+  
+Expand the uclc list using the just defined macro::
+
+  \greek@euenc@update@uclclist
+  
+Now the hiatus definition modifications::
+
+  \DeclareTextCommand{\LGR@A@hiatus}{\LastDeclaredEncoding}{%
+    \LGR@ifnextchar{Ι}{\textAlpha\"}{%
+      \LGR@ifnextchar{Υ}{\textAlpha\"}{%
+        \LGR@ifnextchar{\textIota}{\textAlpha\"}{%
+          \LGR@ifnextchar{\textUpsilon}{\textAlpha\"}{\textAlpha}%
+        }%
+      }%
+    }%
+  }
+  \DeclareTextCommand{\LGR@E@hiatus}{\LastDeclaredEncoding}{%
+    \LGR@ifnextchar{Ι}{\textEpsilon\"}{%
+      \LGR@ifnextchar{Υ}{\textEpsilon\"}{%
+        \LGR@ifnextchar{\textIota}{\textEpsilon\"}{%
+          \LGR@ifnextchar{\textUpsilon}{\textEpsilon\"}{\textEpsilon}%
+        }%
+      }%
+    }%
+  }

 %   ====== ========== =========================================================
-% 
+%
 % Motivation
 % ==========
-% 
+%
 % By default, the ``\alpha, \beta, ...`` macros for Greek letters
 % are only valid in mathematical mode.
-% 
+%
 % 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.
-% 
+%
 % If used together with the ``utf8`` option of inputenc_, literal Unicode
 % characters can be used for Greek symbols in mathematical formulas.
-% 
+%
 % .. Attention::
 %    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.
-% 
+%
 %    Therefore, Greek text should be written with the help of babel_ or
 %    polyglossia_ (setting the language to ``greek``) or wrapped in the
 %    provided ``ensuregreek`` macro.  Using babel_ or polyglossia_ also helps
 %    to ensure proper hyphenation.
