<p class="topic-title first">Abstract</p>
<p>The LGR font encoding is the de-facto standard for Greek
typesetting with (8-bit) LaTeX. However, the encoding definition
file that ships with <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/babel.html">babel</a> misses many of the definitions common
since the advent of the NFSS <a class="citation-reference" href="#fntguide" id="id1">[fntguide]</a>.</p>
<p>The <cite>lgrx</cite> bundle provides packages and definitions for
typesetting Greek text with fonts in the LGR encoding. It works
for both, monotonic and polytonic Greek, independent of the
<cite>babel</cite> package.</p>
<p>The bundle is available from <a class="reference external" href="http://www.ctan.org/pkg/lgrx">CTAN</a> and included in
TeXLive 2012.</p>

<h3><a class="toc-backref" href="#id17">Unicode</a></h3>
<p>The Unicode standard allows fonts that comprise glyphs from (almost) all
known scripts. With the TeX engines XeTeX or LuaTeX, typesetting Greek with
LaTeX is as easy as finding a font that contains Greek letters and setting
it up with <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/fontspec.html">fontspec</a>. Beware, that you must not use the <tt class="literal">greek</tt> or
<tt class="literal">polutonikogreek</tt> options of the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/babel.html">babel</a> package. The <cite>babel</cite> replacement
<a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/polyglossia.html">polyglossia</a> provides Greek language support for XeLaTeX/LuaLaTeX.
If you go this way, you don’t need the lgrx bundle.</p>
</div>
<div class="section" id="t7">
<h3><a class="toc-backref" href="#id18">T7</a></h3>
<p>The <a class="citation-reference" href="#encguide" id="id3">[encguide]</a> reserves the name T7 for a Greek <cite>standard font encoding</cite>.
However, up to now, there is no agreement on an implementation because the
restrictions for general text encodings are too severe for typesetting
polytonic Greek.</p>
</div>
<div class="section" id="lgr">
<h3><a class="toc-backref" href="#id19">LGR</a></h3>
<p>The LGR font encoding is the de-facto standard for typesetting Greek with
(8-bit) LaTeX. Fonts in this encoding include the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/cbgreek-complete.html">CB fonts</a> (matching CM),
<a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/grtimes.html">grtimes</a> (Greek Times), <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/kerkis.html">Kerkis</a> (matching URW Bookman), and the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/gfs.html">GFS font
collection</a>. Setup of these fonts as Greek variant to matching Latin fonts
is facilitated by the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/substitutefont.html">substitutefont</a> package.</p>
<p>The LGR font encoding generates Greek characters via an ASCII
transliteration. This enables simple input with a Latin keyboard.
Characters with diacritics are selected by ligature definitions in the
font (see <a class="citation-reference" href="#greek-usage" id="id4">[greek-usage]</a>, <a class="citation-reference" href="#teubner-doc" id="id5">[teubner-doc]</a>, <a class="citation-reference" href="#cbfonts" id="id6">[cbfonts]</a>).</p>
<p>A major drawback of this transliteration is, 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 <tt class="literal">greek</tt> or <tt class="literal">polutionikogreek</tt>).
This means that for every Latin-written word or acronym an explicite
language-switch is required. This problem can only be solved via a
font-encoding comprising Latin and Greek like the hypothetic <a class="reference internal" href="#t7">T7</a> or Unicode
(with XeTeX or LuaTeX).</p>
</div>
<div class="section" id="ot7">
<h3><a class="toc-backref" href="#id20">*OT7</a></h3>
<p>The name LGR does not reflect status of this font encoding due to historical
reasons. <a class="citation-reference" href="#encguide" id="id7">[encguide]</a> classifies encodings starting with <cite>L</cite> as “local”.
Indeed, LGR started as a local encoding for the <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/cbgreek-complete.html">CB fonts</a> by Claudio
Beccari. Later, Apostolos Syropoulos advanced it to the default font
encoding for the <cite>babel</cite> package’s <tt class="literal">greek</tt> option. A better name would be
OT7:</p>
<ul class="simple">
<li><p>It is an ‘old’ encoding.</p></li>
<li><p>It implements a Latin transcription for a non-Latin script like the
OT2 encoding.</p></li>
<li><p>It is not confined to 128 bit but OT4 shows that this is no
absolute requirement for an <cite>OT</cite> encoding.</p></li>
</ul>
<p>However, due to the fact that the LGR font encoding has been used under its
current name for a long time, the name will not change for compatibility
reasons.</p>

<div class="section" id="problems-with-the-default-setup">
<h2><a class="toc-backref" href="#id21">Problems with the default setup</a></h2>
<p>The <cite>lgrx</cite> budle adresses a set of problems with the LGR font encoding as
set up by <cite>babel</cite>:</p>
<ol class="arabic">
<li><p>Ligatures with prefix notation prevent kerning (see the example document
<a class="reference external" href="lgrxenc-test.pdf">lgrxenc-test.pdf</a> and <a class="citation-reference" href="#teubner-doc" id="id8">[teubner-doc]</a>).</p></li>
<li><p>Sub-optimal results with the standard accent macros:</p>
<ul class="simple">
<li><p>no combined accents,</p></li>
<li><p>accents above (instead of before) capital letters,</p></li>
<li><p>pre-composed characters are not used.</p></li>
</ul>
</li>
<li><p>The tilde character <tt class="literal">~</tt> is used for a non-breaking space by
default. Therefore the transliteration for the <em>perispomeni</em> accent is
not available without re-definition of this character.<a class="footnote-reference" href="#tildehack" id="id9"><sup>1</sup></a></p></li>
<li><p>The <tt class="literal">polutonikogreek</tt> <cite>babel</cite> option redefines both, <tt class="literal">~</tt> and <tt class="literal">\~</tt>
to produce accents via input ligatures (restricted to the language
setting instead of the font encoding). This prevents the placing of a
tilde-accent on non-supported characters like in <em>niño</em> if the language
is set to polytonic Greek, even if <tt class="literal">\textlatin</tt> is used.<a class="footnote-reference" href="#poluhack" id="id10"><sup>2</sup></a></p></li>
<li><p>There is no Unicode support with <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/inputenc.html">inputenc</a>’s <tt class="literal">utf8</tt> option.</p>
<p>The <cite>ucs</cite> package contributed by Dominique Unruh provides Unicode support
with the <tt class="literal">utf8x</tt> option. A babel patch by Werner Lemberg for Greek
Unicode support <a class="citation-reference" href="#lemberg2008" id="id11">[lemberg2008]</a> never got applied.)</p>
