<p>There are several alternatives to set up the support for a Greek font

<dl>
<dt>Babel:</dt>
<dd><p>Use the <span class="docutils literal">greek</span> option with <a class="reference external" href="https://ctan.org/pkg/babel">Babel</a>:</p>

<p>This automatically loads <span class="docutils literal">lgrenc.def</span> with 8-bit TeX and

hyphenation and other localizations (see <a class="reference external" href="https://ctan.org/pkg/babel-greek">babel-greek</a>).</p>
<p>Babel can be used together with <a class="reference internal" href="#textalpha">textalpha</a> or <a class="reference internal" href="#alphabeta">alphabeta</a>.</p>
</dd>
<dt><a class="reference internal" href="#textalpha">textalpha</a>:</dt>

also in LGR</p>
<pre class="literal-block">\usepackage[normalize-symbols,keep-semicolon]{textalpha}</pre>
<p>This sets up LICR macros for Greek text characters under both, 8-bit TeX

<p>Note that without <a class="reference internal" href="#textalpha">textalpha</a> or <a class="reference internal" href="#alphabeta">alphabeta</a>, Greek text macros work

<section id="lgr">
<h3><a class="toc-backref" href="#toc-entry-10" role="doc-backlink">LGR</a></h3>
<p>The LGR font encoding is the de-facto standard for typesetting Greek with
8-bit LaTeX. <cite>greek-fontenc</cite> provides a comprehensive <a class="reference internal" href="#lgr-font-encoding-definition-file">LGR font
encoding definition file</a>.</p>
<p>Fonts in this encoding include the <a class="reference external" href="https://ctan.org/pkg/cbgreek-complete">CB fonts</a> (matching CM), <a class="reference external" href="https://ctan.org/pkg/grtimes">grtimes</a>
(Greek Times), <a class="reference external" href="https://ctan.org/pkg/kerkis">Kerkis</a> (matching URW Bookman), <a class="reference external" href="https://ctan.org/pkg/dejavu">DejaVu</a>, <a class="reference external" href="https://ctan.org/pkg/libertinegc">Libertine GC</a>, and
the <a class="reference external" href="https://ctan.org/pkg/gfs">GFS fonts</a>. Setup of these fonts as Greek variant to
matching Latin fonts is facilitated by the
<span class="docutils literal">\DeclareFontfamilySubstitution</span> command added to the
LaTeX kernel in the 2020-02 release <a class="citation-reference" href="#ltnews31" id="citation-reference-2" role="doc-biblioref">[ltnews31]</a>.</p>
<p>The LGR font encoding allows to access Greek characters via an ASCII
transliteration. This enables simple input with a Latin keyboard.
Characters with diacritics can be selected by ligature definitions in the
font (see <a class="citation-reference" href="#greek-usage" id="citation-reference-3" role="doc-biblioref">[greek-usage]</a>, <a class="citation-reference" href="#teubner-doc" id="citation-reference-4" role="doc-biblioref">[teubner-doc]</a>, <a class="citation-reference" href="#cbfonts" id="citation-reference-5" role="doc-biblioref">[cbfonts]</a>).</p>
<p>A major drawback of the transliteration is the fact, that you cannot
access Latin letters if LGR is the active font encoding (e.g. in
documents or parts of documents given the <cite>Babel</cite> language <span class="docutils literal">greek</span> or
<span class="docutils literal">polutionikogreek</span>). This means that for every Latin-written word or
acronym an explicit language-switch is required. This problem can be
circumvented using Unicode fonts (font encoding <a class="reference internal" href="#tu">TU</a>) with XeTeX or
LuaTeX.</p>
</section>
<section id="tu">
<h3><a class="toc-backref" href="#toc-entry-11" role="doc-backlink">TU</a></h3>
<p>Standard Unicode font encoding for XeTeX and LuaTeX loaded by <a class="reference external" href="https://ctan.org/pkg/fontspec">fontspec</a>

<cite>greek-fontenc</cite> adds support for the Greek script (see <a class="reference internal" href="#tuenc-greek">tuenc-greek</a>).</p>
<p>Xe/LuaTeX works with any system-wide installed <a class="reference external" href="https://ctan.org/topic/font-otf">OpenType font</a>. Suitable
fonts supporting Greek include <a class="reference external" href="https://ctan.org/pkg/cm-unicode">CM Unicode</a>, <a class="reference external" href="http://dejavu-fonts.org">Deja Vu</a>, <a class="reference external" href="https://ctan.org/pkg/ebgaramond">EB Garamond</a>,

<a class="reference external" href="https://ctan.org/pkg/tempora">Tempora</a>, and <a class="reference external" href="https://ctan.org/pkg/umtypewriter">UM Typewriter</a> (all available on CTAN) but also many commercial

Greek characters.</p>
<p>LuaTeX does not apply the NFC normalization by default. This leads to
sub-optimal placing of some diacritics, especially the sub-iota (becoming
unintelligible in combination with small letter eta). This issue can be fixed
specifiying the “Harfbuzz” renderer when loading fonts with fontspec,
e.g.</p>
<pre class="literal-block">\setmainfont[Renderer=Harfbuzz]{FreeSerif}</pre>

<p>The LICR macro names for Greek symbols are chosen pending
endorsement by the TeX community and related packages.</p>
<p>Names for archaic characters, accents/diacritics, and
punctuation may change in future versions.</p>
</aside>
<p>This bundle provides LaTeX internal character representations (LICR macros)
for Greek letters and diacritics. Macro names were selected based on the
following considerations:</p>
<section id="letters-and-symbols">
<h3><a class="toc-backref" href="#toc-entry-16" role="doc-backlink">Letters and symbols</a></h3>
<ul>
<li><p>The <a class="reference internal" href="#fntguide">fntguide</a> (section 6.4 Naming conventions) recommends:</p>
<blockquote>
<p>Where possible, text symbols should be named as <span class="docutils literal">\text</span> followed
by the <strong>Adobe glyph name</strong>: for example <span class="docutils literal">\textonequarter</span> or
<span class="docutils literal">\textsterling</span>. Similarly, math symbols should be named as
<span class="docutils literal">\math</span> followed by the glyph name, for example
<span class="docutils literal">\mathonequarter</span> or <span class="docutils literal">\mathsterling</span>.</p>

<dt>Problem:</dt>
<dd><p>The <a class="reference external" href="http://raw.githubusercontent.com/adobe-type-tools/agl-aglfn/master/aglfn.txt">Adobe Glyph List For New Fonts</a> has names for many glyphs in the
<cite>Greek and Coptic</cite> Unicode block, but not for <cite>Greek extended</cite>. The
<a class="reference external" href="http://raw.githubusercontent.com/adobe-type-tools/agl-aglfn/master/glyphlist.txt">Adobe Glyph List</a> (for existing fonts) lists additional glyph names
used in older fonts. However, these are not intended for active use.</p>
</dd>

</li>
<li><p>If there exists a <strong>math-mode macro</strong> for a symbol, the corresponding text
macro could be formed by prepending <span class="docutils literal">text</span>.</p>
<dl class="simple">
<dt>Example:</dt>
<dd><p>The glyph name for the GREEK SMALL LETTER FINAL SIGMA is <span class="docutils literal">sigma1</span>,
the corresponding math-macro is <span class="docutils literal">\varsigma</span>. The text symbol is
made available as <span class="docutils literal">\textvarsigma</span>.</p>

<li><p>The <a class="reference external" href="http://www.unicode.org/Public/UNIDATA/NamesList.txt">Unicode names list</a> provides standardized descriptive names for all
Unicode characters that use only capital letters of the Latin alphabet.
While not suited for direct use in LICR macros, they can be
converted to LICR macro names via a defined set of transformation rules.</p>
<dl class="simple">
<dt>Example:</dt>
<dd><p><span class="docutils literal">\textfinalsigma</span> is a descriptive alias for
GREEK SMALL LETTER FINAL SIGMA derived via the rules:</p>
<ul class="simple">
<li><p>drop “LETTER” if the name remains unique,</p></li>

<dt>Pro:</dt>

<li><p>Simpler,</p></li>
<li><p>ease of use (less typing, better readability of source text),</p></li>
<li><p>many established text macro names without “text”,</p></li>
<li><p><span class="docutils literal">text</span> prefix does <strong>not</strong> mark a macro as encoding-specific or
“inserting a glyph”. There are e.g. font-changing macros (<span class="docutils literal">\textbf</span>,
<span class="docutils literal">\textit</span>) and encoding-changing macros (<span class="docutils literal">\textcyr</span>).</p></li>
<li><p>There are examples of encoding-specific macros
without the <span class="docutils literal">text</span>-prefix, especially for letters, see <a class="reference internal" href="#encguide">encguide</a>.</p></li>

<dt>Contra:</dt>
<dd><ul class="simple">
<li><p>Less consistent,</p></li>

<p>The font encoding definition files use the <span class="docutils literal">text</span> prefix for symbols.

<ul>
<li><p>standard accent macros (<span class="docutils literal">\DeclareTextAccent</span> definitions in

macros.</p>
<p>However, the <a class="reference external" href="http://raw.githubusercontent.com/adobe-type-tools/agl-aglfn/master/aglfn.txt">Adobe Glyph List For New Fonts</a> maps, e.g., “tonos” and
“dieresistonos” to the spacing characters GREEK TONOS rsp. GREEK DIALYTIKA
TONOS, hence <span class="docutils literal">\texttonos</span> and <span class="docutils literal">\textdieresistonos</span> should be spacing
characters.</p>
</li>
<li><p>textcomp (ts1enc.def) defines <span class="docutils literal"><span class="pre">\capital...</span></span> accents (i.e. without

<p>Currently, <cite>greek-fontenc</cite> uses for diacritics:</p>
<ul class="simple">
<li><p>Greek names like in Unicode, and <span class="docutils literal">ucsencs.def</span>, and</p></li>
<li><p>the prefix <span class="docutils literal">\acc</span> to distinguish the macros as <cite>TextAaccent</cite> and
reduce the risk of name clashes with spacing characters.</p></li>

<p>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).</p>
<p>The variations have no syntactic meaning in Greek text and Greek text
fonts use the shape variants indiscriminately (cf. <a class="reference external" href="http://en.wikipedia.org/wiki/Greek_alphabet#Glyph_variants">glyph variants</a>).
The variant shapes are not given separate code-points in the <a class="reference internal" href="#lgr">LGR</a> text
font encoding.</p>
<p>In mathematical mode, TeX supports the alternative glyph variants with
<span class="docutils literal">\var<lettername></span> macros (variant macros for ϴ, ϐ, and ϰ require
additional packages).</p>
<p>Unicode defines separate code points for the symbol variants for use in
mathematical context.<a class="superscript" href="#footnote-3" id="footnote-reference-3" role="doc-noteref"><span class="fn-bracket">[</span>3<span class="fn-bracket">]</span></a> Unfortunately, the mapping between Unicode’s
letter/symbol distinction and “normal”/variant in TeX is inconsistent.</p>
<p><cite>greek-fontenc</cite> provides <span class="docutils literal">\text<lettername>symbol</span> LICR macros for the
Greek symbol characters:</p>
<ul>
<li><p>With Unicode fonts, the macros select the GREEK <lettername> SYMBOL``.</p></li>
<li><p>With LGR encoded fonts, they report an error by default.</p>
<p>With the <span class="docutils literal"><span class="pre">normalize-symbols</span></span> option of <a class="reference internal" href="#textalpha">textalpha</a> and <a class="reference internal" href="#alphabeta">alphabeta</a>,
they are mapped to the corresponding letter (loosing the distinction
between the shape variants).</p>
</li>
</ul>
<p>The <a class="reference internal" href="#alphabeta">alphabeta</a> package provides <span class="docutils literal">\<lettername></span>, <span class="docutils literal">\var<lettername></span>,
and <span class="docutils literal">\<lettername>symbol</span> in both, text and math mode (cf. Table 1 in
