<p>The LGR font encoding is the de-facto standard for Greek
typesetting with LaTeX. This file provides a comprehensive set
of macros to typeset Greek with LGR encoded fonts. It works for
both, monotonic and polytonic Greek, independent of the <cite>babel</cite>

<h1><a class="toc-backref" href="#id3">preliminary considerations: LICR macro names</a></h1>
<p>This file provides LaTeX internal character representations (LICR macros)
for all non-ASCII characters present in the LGR font encoding. For Greek
letters and diacritics, LICR macro names were selected based on the
following considerations:</p>
<p>The <a class="reference external" href="http://mirror.ctan.org/macros/latex/doc/fntguide.pdf">fntguide</a> (section 6.4 Naming conventions) recommends:</p>
<blockquote>
<p>Where possible, text symbols should be named as <tt class="literal">\text</tt> followed
by the Adobe glyph name: for example <tt class="literal">\textonequarter</tt> or
<tt class="literal">\textsterling</tt>. Similarly, math symbols should be named as
<tt class="literal">\math</tt> followed by the glyph name, for example
<tt class="literal">\mathonequarter</tt> or <tt class="literal">\mathsterling</tt>.</p>
</blockquote>
<p>The <a class="reference external" href="http://www.adobe.com/devnet-archive/opentype/archives/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://partners.adobe.com/public/developer/en/opentype/glyphlist.txt">Adobe Glyph List</a> (for existing fonts) lists additional glyph names
used in older fonts.</p>
<div class="section" id="proposals">
<h2><a class="toc-backref" href="#id4">Proposals</a></h2>
<ul>
<li><p>If there exists a math-mode macro for a symbol, form the corresponding text
macro by prepending <tt class="literal">text</tt>?</p>
<dl class="docutils">
<dt>Example:</dt>
<dd><p>The glyph name for the GREEK SMALL LETTER FINAL SIGMA is <tt class="literal">sigma1</tt>,
the corresponding math-macro is <tt class="literal">\varsigma</tt>. The text symbol could be
made available as <tt class="literal">\textvarsigma</tt>.</p>
</dd>
<dt>Problems:</dt>
<dd><p><tt class="literal">\varepsilon</tt> and <tt class="literal">\varphi</tt> math macros map to characters named
“GREEK SMALL <strong>LETTER</strong> …”, while <tt class="literal">\\vartheta</tt>, <tt class="literal">\\varkappa</tt>,
<tt class="literal">\\varrho</tt>, and <tt class="literal">\\varpi</tt> math macros map to “GREEK … <strong>SYMBOL</strong>”
Unicode characters.</p>
<p>In Greek text, these variants are interchangeable. The LGR font encoding
does not contain slots for “symbol” glyph variants. In some Greek fonts,
GREEK SMALL LETTERS use glyph variants resembling the corresponding
GREEK SYMBOL Unicode character’s reference glyph.</p>
</dd>
</dl>
</li>
<li><p>Derive macro names from Unicode names?</p>
<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 a LICR macros, they can be either</p>
<ol class="loweralpha simple">
<li><p>used as inspiration for new LICR macro names or</p></li>
<li><p>converted to LICR macro names via a defined set of transformation rules.</p></li>
</ol>
<dl class="docutils">
<dt>Example:</dt>
<dd><p><tt class="literal">\textfinalsigma</tt> or just <tt class="literal">\finalsigma</tt> as a more descriptive name
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>
<li><p>drop “GREEK” if the name remains unique,</p></li>

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

<li><p>tipa.sty and ucs use the “text” prefix also for accents.</p>
<p>However, the <a class="reference external" href="http://www.adobe.com/devnet-archive/opentype/archives/aglfn.txt">Adobe Glyph List For New Fonts</a> maps, e.g., “tonos” and
“dieresistonos” to 0384 GREEK TONOS and 0385 GREEK DIALYTIKA TONOS, hence
<cite>texttonos</cite> and <cite>textdiaresistonos</cite> should be spacing characters.</p>
</li>
<li><p>textcomp (ts1enc.def) defines <tt class="literal"><span class="pre">\capital...</span></tt> accents (i.e. without

<h2><a class="toc-backref" href="#id19">Diacritics</a></h2>
<p>This section defines <a class="reference internal" href="#named-macros">named macros</a> for Greek diacritics and standard
<a class="reference internal" href="#symbol-macros">symbol macros</a> as alias for simple diacritics. Convenient input
conventions for <a class="reference internal" href="#composite-diacritics">composite diacritics</a> are defined as <a class="reference internal" href="#composite-definitions">composite

<p>Advantages:</p>
<ul class="simple">
<li><p>input convention similar to LGR input encodings (just prepend a <tt class="literal">\</tt>).</p></li>
<li><p>Access pre-composed characters without resorting to the
ligature mechanism (allows proper kerning, cf. <a class="reference external" href="http://mirror.ctan.org/macros/latex/contrib/teubner/teubner-doc.pdf">teubner-doc</a>).</p></li>
<li><p>Named macros can be used to ensure a font encoding supporting Greek is
used. However, substitution with pre-composed characters works only for
the active font encoding (cf. <a class="reference external" href="textalpha.sty.html">textalpha</a>). Named accent macros can also be
used instead of the <tt class="literal">\&#64;tabacckludge</tt> by to-LaTeX converters to ensure
working also inside the tabbing environment.</p></li>
<li><p>Named macros are required for upcasing according to Greek typesetting
conventions (cf. <a class="reference internal" href="#uppercase">UPPERCASE</a> below) and for composite diacritics.</p></li>

<h3><a class="toc-backref" href="#id20">Named macros</a></h3>
<p>Definitions are based on the <a class="reference external" href="http://www.ctan.org/pkg/teubner">teubner</a> package by Claudio Beccari, the <a class="reference external" href="http://www.ctan.org/pkg/unicode">ucs</a>
package, and the <a class="reference external" href="http://www.eutypon.gr/eutypon/pdf/e2008-20/e20-a03.pdf">babel patch</a> by Werner Lemberg. Names are derived from
the Unicode name with the prefix “acc” (cf. <a class="reference internal" href="#how-to-name-accent-macros">How to name accent macros?</a>
above) reducing the probability of incompatibilities compared to the
two-letter <a class="reference external" href="http://www.ctan.org/pkg/teubner">teubner</a> diacritic macros or the “text” prefix used by <a class="reference external" href="http://www.ctan.org/pkg/unicode">ucs</a>.</p>

<p>The sub-iota is input after the base character. In LGR fonts, ligatures are

<li><p>The glyph No 12 is a special “Upcase Alpha” that in ligature with Y
and I adds a diaresis to them. However, it seems that it has only
kerning definitions for I and Y (as it is not intended for direct
use)</p>

<p>No such glyph exists for E but this is no problem as E does
not require kerning anyway.</p>
