<h2><a class="toc-backref" href="#toc-entry-1" role="doc-backlink">Motivation</a></h2>
<p>By default, TeX macros for Greek letters are only valid in mathematical
mode. This package sets up a suitable <a class="reference internal" href="#font-encoding">font encoding</a> and <cite>LaTeX internal
character representations</cite> (LICR) definitions for Greek (<span class="docutils literal">\textalpha</span> –
<span class="docutils literal">\textOmega</span>).</p>
<p>To allow documents using Greek LICR macros without worrying about the TeX
engine used to compile them, this package tests the declared font encodings
and does “the right thing” to set up Greek text font support:</p>
<ul class="simple">
<li><p>If an Unicode font encoding is declared by <span class="docutils literal">fontspec</span>, add Greek LICR
definitions.</p></li>
<li><p>Otherwise, the <a class="reference external" href="README.html#lgr">LGR font encoding</a> is set as <cite>default font encoding</cite>
(cf. <a class="citation-reference" href="#" id="citation-reference-1" role="doc-biblioref">[fntguide]</a> section 5.3) for Greek.</p></li>
</ul>
<p>Advantages:</p>
<ul>
<li><p>Symbols from a Greek text font (e.g. the <a class="reference external" href="https://ctan.org/pkg/cbgreek-complete">CB fonts</a>) can be accessed
without the need for an explicite font-encoding switch anywhere in the
text.</p></li>
<li><p>Unicode input of Greek characters is supported</p>
<ul>
<li><p>via <span class="docutils literal"><span class="pre">\usepackage[utf8]{inputenc}</span></span> and <span class="docutils literal">lgrenc.dfu</span> from
<a class="reference external" href="https://ctan.org/pkg/greek-inputenc">greek-inputenc</a> for 8-bit TeX or XeTeX/LuaTeX in 8-bit compatibility
mode in any font encoding (see <a class="reference external" href="textalpha-doc.tex">textalpha-doc.tex</a>).</p></li>
<li><p>natively by XeTeX/LuaTeX for Unicode fonts.</p>
<p>If 8-bit font encodings like LGR are used alongside Unicode fonts, text
input can be done via the Latin transliteration or LICR but <em>not via
literal Unicode characters</em> (see <a class="reference external" href="test-tuenc-greek.tex">test-tuenc-greek.tex</a>).</p>
</li>
</ul>
</li>
</ul>
<aside class="admonition attention" id="limitations">
<p class="admonition-title">Attention!</p>
<p>The macros work well in any font encoding for single symbols.
However, with 8-bit TeX engines, 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="https://ctan.org/pkg/babel">babel</a> or
<a class="reference external" href="https://ctan.org/pkg/polyglossia">polyglossia</a> (setting the language to <span class="docutils literal">greek</span>) or wrapped in the
provided <span class="docutils literal">ensuregreek</span> macro. Using <a class="reference external" href="https://ctan.org/pkg/babel">babel</a> or <a class="reference external" href="https://ctan.org/pkg/polyglossia">polyglossia</a> also helps
to ensure correct hyphenation and upcasing of Greek text.</p>

<p>With 8-bit LaTeX, the <a class="reference external" href="README.html#lgr">LGR font encoding</a> is used for Greek characters. If
no Greek-supporting font encoding (TU or LGR) is declared, LGR is
loaded and set up as default Greek font encoding by this package.</p>
<p>With XeTeX or LuaTeX, there is one common input and font encoding –
Unicode. 8-bit TeX font encodings are only used in compatibility mode or for
fonts not available otherwise. For compatibility with the LaTeX font
selection system, <a class="reference external" href="https://ctan.org/pkg/fontspec">fontspec</a> defines the TU font encoding. However
<cite>fontspec</cite> does not define Greek LICR macros. We therefore explicitely
load Greek LICR definitions for XeTeX/LuaTeX from <a class="reference external" href="tuenc-greek.def.html">tuenc-greek.def</a> which in turn includes <a class="reference external" href="greek-fontenc.def.html">greek-fontenc.def</a>.</p>
<p>Ensure a Greek-supporting font encoding exists and supports Greek LICR
macros:</p>
<pre class="literal-block">\ifdefined \UnicodeEncodingName % set by LaTeX for Unicode-aware engines
\input{tuenc-greek.def}
\textalpha@define@breathings{\UnicodeEncodingName}
\else
\@ifl@aded{def}{lgrenc}
{}
{\input{lgrenc.def}
}
\fi</pre>
<p>LGR may also be used in a document compiled with Xe/LuaTeX
(enables use of 8-bit TeX fonts and input via the Latin transliteration).
Add setup for breathings:</p>
<pre class="literal-block">\@ifl@aded{def}{lgrenc}
{\textalpha@define@breathings{LGR}}
{}</pre>
<p>The package <a class="reference external" href="https://ctan.org/pkg/hyperref">hyperref</a> defines the PU font encoding and adds some
LICR commands for monotonic Greek (in punenc-greekbasick.def).
Add support for polytonic Greek, archaic symbols,
and the <span class="docutils literal">\greekscript</span> and <span class="docutils literal">\ensuregreek</span> TextCommands:</p>
<pre class="literal-block">\AtBeginDocument{
\@ifl@aded{def}{puenc}

<p>The TS1 font encoding (available by default since 2022) provides a

<p>The <span class="docutils literal">\greekscript</span> declaration ensures the current font encoding supports
the Greek script. <span class="docutils literal"><span class="pre">greek-fontenc.def</span></span> sets this to the empty declaration
for font encodings that do so. This is currently used by <span class="docutils literal">lgrenc.def</span>
(LGR) and <span class="docutils literal"><span class="pre">tuenc-greek.def</span></span> (Greek LICR macros for TU, EU1, or EU2).</p>
<p>We define LGR as default encoding for Greek text. We use
<span class="docutils literal">\ProvideTextCommandDefault</span> to enable the author or other packages to use
an alternative definition (see [<a class="reference external" href="https://mirrors.ctan.org/macros/latex/base/fntguide.pdf">fntguide</a>]):</p>
<pre class="literal-block">\ProvideTextCommandDefault{\greekscript}{\fontencoding{LGR}\selectfont
\def\encodingdefault{LGR}}</pre>
<p>The <span class="docutils literal">\ensuregreek</span> command can be used to ensure that its argument is set in
a font encoding with support for Greek. Again the default is LGR:</p>
<pre class="literal-block">\ProvideTextCommandDefault{\ensuregreek}[1]{\leavevmode{\greekscript #1}}</pre>
<!-- The [fntguide_] writes
Note that ``\DeclareTextAccentDefault`` can be used on any
one-argument encoding-specific command, not just those defined with
``\DeclareTextAccent``.
However, the simpler alternative
``\DeclareTextAccentDefault{\ensuregreek}{LGR}`` fails with the table of
Unicode characters in the test document `<textalpha-doc.tex>`__:
``! You can't use a prefix with `end-group character }'.`` -->
<p>Eventually, all font encodings supporting Greek script (e.g. LGI, PU, TU)
will declare <span class="docutils literal">\ensuregreek</span> as text command that passes the
argument unchanged. This way, kerning and selection of precomposed glyphs
would work also for cases like <span class="docutils literal"><span class="pre">\ensuregreek{\'A}U</span></span>.</p>

<h4><a class="toc-backref" href="#toc-entry-18" role="doc-backlink">semicolon as erotimatiko</a></h4>
<p>The text command <span class="docutils literal">\textsemicolon</span> inserts <span class="docutils literal">\texterotimatiko</span>
in LGR font encoding and a “normal” semicolon else.
In math mode, it inserts the “normal” semicolon also if the text font
encoding is LGR:</p>
<pre class="literal-block">\ProvideTextCommandDefault{\textsemicolon}{;}
\ProvideTextCommand{\textsemicolon}{LGR}{\texterotimatiko}</pre>
<p>The LGR font encoding maps “;” to a middle dot (ano teleia). With the
<a class="reference internal" href="#keep-semicolon">keep-semicolon</a> option, the semicolon is made an active character and calls
<span class="docutils literal">\textsemicolon</span>:</p>
<pre class="literal-block">\iftextalpha@keepSemicolon
\catcode`;=\active
\newcommand{;}{\TextOrMath{\textsemicolon}{\char59}}

<li><p>Load <span class="docutils literal">lgrenc.def</span> rsp. <span class="docutils literal"><span class="pre">tuenc-greek.def</span></span> after the common definitions
and after <span class="docutils literal"><span class="pre">puenc-greek.def</span></span>?</p>
<blockquote>
<p>If an encoding-specific command is defined for more than one encoding,
then it will execute fastest in the encoding in which it was defined
last since its top-level definition will be set up to execute in that
encoding without any overhead.</p>
<p>…</p>
<p>For the same reason default declarations should never come last since
they are implemented as a special encoding themselves (with the name “?”).
Specifying them last would simply mean to make those encoding-specific
commands equally inefficient in all encodings.</p>
