-\title{The \emph{textalpha} package}
-\author{Günter Milde}
-\maketitle
-
-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 the utf8
-option to \href{http://www.ctan.org/pkg/inputenc}{inputenc}) Unicode literals.

-\section{Greek Unicode characters in non-Greek text}
-
-With the \emph{textalpha} package and input encoding \texttt{utf8}, Greek
-Unicode characters can be used in text with any font encoding.
-
-Kerning is preserved if the font encoding is LGR. This holds also for
-pre-composed accented characters: \ensuregreek{AΫA}.
-
-All characters of the Greek and Coptic Unicode Block present in LGR via
-literal Unicode input in T1 font encoding
-(legend: * glyph missing in LGR):
-

-Combined Diacritics work ᾅ, diacritics (except diaeresis) are dropped with
-MakeUppercase (μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}).
-

-\section{PDF strings}
-
-With \emph{textalpha}, you can get Greek letters in PDF strings, too.
-
-\subsection{\textlambda\textomicron\textgamma\textomicron\textvarsigma{},
- λογος and \ensuregreek{logos}}
-
-The subsection title above uses: text* macros, Unicode input and the LGR
-transcription for the Greek word \ensuregreek{logos}. Check the table of
-contents in the PDF viewer: text* macros and Unicode literals work fine, the
-Latin transcription stays Latin in the PDF metadata.
-
-
-\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) or 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.}).
-
-\subsection{Diacritics}
-
-Composition of diacritics (like \verb|\accdasia\acctonos|) fails in other
-font encodings. Long names (like \verb|\accdasiaoxia|) work, however they do
-not select pre-composed characters. With LGR, pre-composed glyphs are chosen
-if available (the difference becomes obvious if you drag-and-drop text from
-the PDF version of this document):
-%
-\ensuregreek{\<'a \accdasia\acctonos a \accdasiaoxia a
-\accdasiaoxia\textalpha} (LGR) vs. \accdasiaoxia\textalpha{} (T1).
-
-According to Greek typographical tradition, diacritics (except the
-dialytika) are placed before capital letters in titlecase and dropped in
-all-caps:
-%
-\begin{quote}
- \ensuregreek{%
- \<{\textalpha} \>{\textepsilon} \"'{\textiota} \`>\texteta{}
- \'<{\textomicron} \~<{\textupsilon} \~>{\textomega}
- \\
- \<{\textAlpha} \>{\textEpsilon} \"{\textIota} \`>\textEta{}
- \'<{\textOmicron} \~<{\textUpsilon} \~>{\textOmega}
- \\
- \MakeUppercase{%
- \<{\textalpha} \>{\textepsilon} \"'{\textiota} \`\>\texteta{}
- \'<{\textomicron} \~<{\textupsilon} \~>{\textomega}.
- }
- }
-\end{quote}
-%
-This fails if the active font encoding is not LGR:
-\ensuregreek{\'\textAlpha} (LGR) vs. \'\textAlpha (T1).
-To overcome this, the \verb|\ensuregreek| macro is used in composite Unicode
-character definitions: \ensuregreek{Ά} (LGR) = Ά (T1).
-
-
-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 font encoding only:
-\acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{} $\mapsto$
-\MakeUppercase{\ensuregreek{
- \acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{}
-}} vs.
-\MakeUppercase{
- \acctonos\textalpha\textupsilon{}, \acctonos\textepsilon\textiota{}%
-}.
-
-Currently, the second vowel of the diphthong must be given as macro, not
-Unicode literal if the auto-hiatus feature should work:
-\ensuregreek{ἀ\textupsilon{}πνία} $\mapsto$
-\ensuregreek{\MakeUppercase{\ensuregreek{ἀ\textupsilon{}πνία}}} vs.
-\ensuregreek{\MakeUppercase{\ensuregreek{ἀυπνία}}}.
-
-\subsection{Kerning}
-
-No kerning occurs between Greek characters in non-Greek text due to the
-internal font encoding switch: compare
-\ensuregreek{\textAlpha\textUpsilon\textAlpha} (LGR) to
-\textAlpha\textUpsilon\textAlpha (T1).
