\title{Greek Unicode with 8-bit TeX and \emph{inputenc}}
\author{Günter Milde}
\maketitle
\abstract{ The definitions in \texttt{lgrenc.dfu} provide UTF-8 support for
the Greek script based on \emph{inputenc} and the \emph{LaTeX internal
character representation} macros (LICRs) defined in the \emph{greek-fontenc}
package.
\section{Requirements}
The \href{http://www.ctan.org/pkg/inputenc}{\emph{inputenc}} standard
package enables the use of non-ASCII characters with 8-bit TeX. However, it
misses definitions for Greek characters. The \emph{greek-inputenc} package
extends \emph{inputenc} to allow the use of Greek literals in the document
source.
As with all \emph{inputenc} definitions, this only works if the active font
encoding supports the characters. For the Greek script, this is usually the
non-standard \emph{LGR} font encoding set up by
\href{http://www.ctan.org/pkg/greek-fontenc}{\emph{greek-fontenc}}.
% e.g. Π produces:
% ! LaTeX Error: Command \textPi unavailable in encoding T1.
% just like Ж produces:
% ! LaTeX Error: Command \CYRZH unavailable in encoding T1.
\section{Usage}
There are several alternatives to activate Greek Unicode input for 8-bit TeX%
\footnote{
The XeTeX and LuaTeX engines use utf8 as native input encoding. They do
not require (and, except in 8-bit compatibility mode, do not work with)
the \emph{inputenc} and \emph{greek-inputenc} packages.}
%
(see also the source document \url{greek-utf8.tex}):
\begin{itemize}
\item
Define the LGR font encoding and the UTF8 input encoding (the order does not
matter), e.g.,
%
\begin{verbatim}
\usepackage[T1,LGR]{fontenc}
\usepackage[utf8]{inputenc}
\end{verbatim}
%
Ensure that LGR is the active font encoding whenever a Greek character is
used in the text (see below).
\item
For text in the Greek language, it is recommended to use the
\href{http://www.ctan.org/pkg/babel}{\emph{Babel}} package with the Greek
language definitions in
\href{http://www.ctan.org/pkg/babel-greek}{\emph{babel-greek}}. Babel sets
the font encoding automatically to LGR and Greek Unicode characters work as
expected. Write in the preamble, e.g.,
%
\begin{verbatim}
\usepackage[utf8]{inputenc}
\usepackage[LGR,T1]{fontenc}
\usepackage[english,greek,german]{babel}
\end{verbatim}
%
and use \verb+\foreignlanguage+ or \verb+\selectlanguage+ to set the text
language to Greek (see the
\href{http://www.ctan.org/pkg/babel-greek}{\emph{babel-greek}} documentation
for detailled examples).
\begin{quote}
\greekscript
Τί φήις; Ἱδὼν ἐνθέδε παῖδ’ ἐλευθέραν
τὰς πλησίον Νύμφας στεφανοῦσαν, Σώστρατε,
ἐρῶν άπῆλθες εὐθύς;
\end{quote}
\item
In combination with the \emph{textalpha} package from
\href{http://www.ctan.org/pkg/greek-fontenc}{\emph{greek-fontenc}}, Greek Unicode
characters can be used in text with any font encoding -- just like the
symbols provided by the ``textcomp'' package (i.e. with some limitations
described in
\href{http://mirrors.ctan.org/language/greek/greek-fontenc/textalpha-doc.pdf}%
{textalpha-doc}). With the preamble lines
%
\begin{verbatim}
\usepackage[utf8]{inputenc}
\usepackage{textalpha}
\end{verbatim}
%
it is straightforward to write about π-mesons, γ-radiation, or a 50\,kΩ
resistor.
\item
In combination with the \emph{alphabeta} package (also from
\href{http://www.ctan.org/pkg/greek-fontenc}{\emph{greek-fontenc}}),
Greek Unicode literals can also be used in math mode:
%
\begin{verbatim}
\usepackage[utf8]{inputenc}
\usepackage{alphabeta}
\end{verbatim}
\[
\tan β = \frac{\sin β}{\cos β}.
\]
\end{itemize}
\section{Warning: unsafe ASCII input}
LGR is no ``standard font encoding''. Latin characters and some other ASCII
symbols are mapped to Greek equivalents if LGR is the active font encoding.
(See
\href{http://mirrors.ctan.org/macros/latex/contrib/babel-contrib/greek/usage.pdf}{usage.pdf}
for a description of this Latin-Greek transliteration.)
This means you need an explicit language and/or font-encoding switch for
Latin words and abbreviations in Greek text, e.g., not
\foreignlanguage{greek}{((ηία αντίσταση 750-kΩ))} but
\foreignlanguage{greek}{((ηία αντίσταση 750-\textlatin{k}Ω))}
Special care is also required with the question mark characters:
\begin{itemize}
\item The Unicode standard says character 003B SEMICOLON and not 037E GREEK
QUESTION MARK, is the preferred character for a `Greek question
mark' (erotimatiko),
\item The LGR font encoding maps a SEMICOLON to a middle dot (ano teleia),
while the Latin question mark ``?'' is mapped to the erotimatiko.
\end{itemize}
As a result, only the deprecated character 037E GREEK QUESTION MARK works
with both, Xe/LuaTeX and 8-bit TeX. Compare the source \url{greek-utf8.tex}
and the PDF output:
\begin{center}
\begin{tabular}{lll}
Latin (T1) & Greek (LGR) & question mark character \\
\midrule
Τί φήις; & \foreignlanguage{greek}{Τί φήις;} & 037E GREEK QUESTION MARK \\
Τί φήις; & \foreignlanguage{greek}{Τί φήις;} & 003B SEMICOLON \\
Τί φήις? & \foreignlanguage{greek}{Τί φήις?} & 003F QUESTION MARK \\
\end{tabular}
\end{center}
\section{Supported Characters}
Unicode definitions exist for all non-ASCII characters that can be rendered
with an LGR-encoded font.

\section{Test up/downcasing}
Capital Greek letters have diacritics (except the dialytika) to the left
(instead of above) and drop them in uppercase, e.g.
\foreignlanguage{greek}{μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}}.
Tonos and dasia on the first vowel of a diphthong (\ensuregreek{άι, άυ, έι})
imply a \emph{hiatus}. A dialytika must be placed on the second
vowel if they are dropped (\ensuregreek{\MakeUppercase{\'ai, \'au, \'ei}}).
The auto-hiatus feature in lgrxenc.def works with the Latin
transcription and with character-macros (%
\ensuregreek{\MakeUppercase{%
\'ai,
\'\textalpha \textupsilon,
\'\textepsilon \textiota
}})
and also if the first character is wrapped in \verb+\ensuregreek+ (as done by
the lgrenc.dfu definition for accented characters) or a literal Unicode
character
(\ensuregreek{\MakeUppercase{%
\ensuregreek{\'\textalpha}\textiota,
ά\textupsilon,
ά\textiota
}})
but not if the second character of the diphthong is a Unicode literal
(\ensuregreek{\MakeUppercase{%
\'\textalpha ι,
άυ,
\'\textepsilon ι
}}).
Therefore, the diaresis is missing in the following examples:
\ensuregreek{άυλος $\mapsto$ \MakeUppercase{άυλος},
ἄυλος $\mapsto$ \MakeUppercase{ἄυλος},
μάινα $\mapsto$ \MakeUppercase{μάινα},
κέικ, $\mapsto$ \MakeUppercase{κέικ},
ἀυπνία $\mapsto$ \MakeUppercase{ἀυπνία}}.
Fixing this shortcoming requires knowledge of what
\verb+\LGR@ifnextchar+ ``sees'' when the next character is an upcased
Unicode literal.
As an ugly workaround, use \verb+\textiota+ resp. \verb+\textupsilon+
for the character that should get the diaresis:
\ensuregreek{ἀ\textupsilon{}πνία $\mapsto$ \MakeUppercase{ἀ\textupsilon{}πνία}}.
The following subsections test MakeUppercase and MakeLowercase with all
characters defined in lgrenc.dfu:
\subsection{Greek and Coptic}
\newcommand{\GreekAndCoptic}{ʹ͵ͺ; ΄ ΅Ά·ΈΉΊΌΎΏΐΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩΪΫϘϚϜϠ}
\newcommand{\greekandcoptic}{άέήίΰαβγδεζηθικλμνξοπρςστυφχψωϊϋόύώϙϛϝϟϡ}
Characters of the Greek and Coptic Unicode Block:
\begin{quote}
\selectlanguage{greek}
\GreekAndCoptic\\
\greekandcoptic
\end{quote}
MakeUppercase:
\begin{quote}
\selectlanguage{greek}
\MakeUppercase{\GreekAndCoptic}\\
\MakeUppercase{\greekandcoptic}
\end{quote}
Letters and ypogegrammeni upcased, tonos dropped, dialytika kept.
There is no capital Koppa in LGR, therefore \ensuregreek{ϟ} is left unchanged
with MakeUppercase.
MakeLowercase:
\begin{quote}
\selectlanguage{greek}
\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}}.
\subsection{Greek extended}
MakeUppercase:
% \selectlanguage{greek}
\MakeUppercase{ ἀ ἁ ἂ ἃ ἄ ἅ ἆ ἇ Ἀ Ἁ Ἂ Ἃ Ἄ Ἅ Ἆ Ἇ }\\
