<dt>The LGR font encoding is the de-facto standard for Greek</dt>
<dd><p>typesetting with LaTeX. However, the encoding definition
file that ships with babel misses many of the definitions
common since the advent of the NFSS (see <a class="reference external" href="http://mirror.ctan.org/macros/latex/doc/fntguide.pdf">fntguide</a> "Encodings").</p>
<p>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>

<p>To prevent confusion with <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/babel.html">Babel</a>'s rudimentary <tt class="literal">lgrenc.def</tt>, this file is

<cite>LGRx</cite> and <cite>LGR</cite>, e.g.</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>Open questions:</p>
<ul>
<li><p>Can we omit the <tt class="literal">text</tt> prefix for macros that are already
established in short form (e.g. via babel's <tt class="literal">greek.ldf</tt>) and do
not have a math counterpart?</p>
<dl class="docutils">
<dt>Pro:</dt>
<dd><ul>
<li><p>Simpler.</p></li>
<li><p>Ease of use (less typing, better readability of source text).</p></li>
<li><p>Backwards compatible (many established macro names).</p></li>
<li><p>There are examples of encoding-specific macros
without the <tt class="literal">text</tt>-prefix, especially for letters:</p>
<ul class="simple">
<li><p><tt class="literal">\AE \DH \DJ \L \NG \OE \O \SS \TH \ae \dh \dj \guillemotleft</tt>

<tt class="literal">puenc.def</tt>)</p></li>

<p>as there are e.g. font-changing macros (<tt class="literal">\textbf</tt>, <tt class="literal">\textit</tt>)
and encoding-changing macros (<tt class="literal">\textgreek</tt>, <tt class="literal">\textcyr</tt>).</p>
</li>
</ul>
</dd>
<dt>Contra:</dt>
<dd><ul class="simple">
<li><p>Less consistent.</p></li>

<li><p>How to name <em>accent macros</em> (<tt class="literal">\DeclareTextAccent</tt> definitions)?</p>
<ul class="simple">
<li><p>Should <tt class="literal">\texttonos</tt> be an accent macro or a spacing character?</p></li>
<li><p>How about a common prefix <tt class="literal"><span class="pre">\accent...</span></tt> or postfix <tt class="literal"><span class="pre">\...Accent</span></tt>?</p></li>
</ul>
</li>
<li><p>How about glyph names with numbers and dots?</p>
<ul>
<li><p>Adobe recommends <tt class="literal">uni</tt> (or <tt class="literal">u</tt>) + Unicode number for all
Unicode characters without established name.</p>
<p>While it is <em>possible</em> to apply this scheme to TeX macros, it is
hardly advisable: <tt class="literal">\koppa</tt> is far better readable than
<tt class="literal">\csname uni03DF\endcsname</tt>.</p>
</li>
</ul>
</li>
<li><p>If there exists a math-mode macro for a symbol, the corresponding text
macro should be formed by prepending <tt class="literal">text</tt>.</p>
<blockquote>
<p>Example: The glyph name for the final sigma is <tt class="literal">sigma1</tt>, but the
corresponding math-macro is <tt class="literal">\varsigma</tt>. IMO, the text symbol
should be available as <tt class="literal">\textvarsigma</tt> and not
<tt class="literal">\csname textsigma1\endcsname</tt>.</p>
</blockquote>
<p>Could this become a general rule?</p>

<p>The <a class="reference external" href="http://www.adobe.com/devnet/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>.</p>
<p>An alternative, more complete set of short mnemonic character names is
the <a class="reference external" href="http://www.w3.org/TR/xml-entity-names/">XML Entity Definitions for Characters</a> W3C Recommendation from
01 April 2010.</p>
<p>For glyph names of the LGR encoding see e.g. <tt class="literal">CB.enc</tt> by Apostolos
Syropoulos and <tt class="literal"><span class="pre">xl-lgr.enc</span></tt> from the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/libertine-legacy.html">libertine</a> (legacy) package.
<tt class="literal">lgr.cmap</tt> provides a mapping to Unicode characters.</p>
<p>A full set of <tt class="literal">\text*</tt> symbol macros is defined in <tt class="literal">ucsencs.def</tt>
from the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/unicode.html">ucs</a> package.</p>
<p>Using the names from <tt class="literal">puenc.def</tt> ensures that the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/hyperref.html">hyperref</a> package
will do the right conversion to a PDF-string
(see <a class="reference external" href="greek-part-of-puenc.def">greek-part-of-puenc.def</a>).</p>
<p>For accent macros, this file uses Greek names like in Unicode and
ucsencs.def (without <tt class="literal">text</tt> prefix). Accent macro names are Capitalized or
CamelCase, as they are intended for use in packages or classes. For the
end-user "symbol macros" (<tt class="literal">\~ \' \` \" \< \></tt>) are provided.</p>

<p>Based on the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/teubner.html">teubner</a> package by Claudio Beccari and the <a class="reference external" href="http://www.eutypon.gr/eutypon/pdf/e2008-20/e20-a03.pdf">babel
patch</a> by Werner Lemberg but with composite diacritic definitions
(iterative diacritics).</p>
<p>Advantages:</p>
<ul class="simple">
<li><p>get accented 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>reduced probability of incompatibilities (compared to <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/teubner.html">teubner</a>
diacritic macros).</p></li>
<li><p>input convention similar to LGR input encodings (just prepend a <tt class="literal">\</tt>).</p></li>

<div class="section" id="simple-diacritics">
<h3><a class="toc-backref" href="#id16">simple diacritics</a></h3>
<p>Define Greek diacritics as named macros with shortcut alias.</p>
<p>Direct defining of <tt class="literal">\<</tt> and <tt class="literal">\></tt> fails with
<tt class="literal">`! Missing $ inserted.'</tt> (clash with math definitions).
Also, we need aliases for proper upcasing (cf. <a class="reference internal" href="#uppercase">UPPERCASE</a> below).</p>
