<p class="topic-title">Abstract</p>
<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>
package.</p>

<p>The LICR macros provide a way to access the symbols independent of the
specific font encoding, in any font encoding supporting Greek. An
alternative Greek font encodings is LGI (<a class="reference external" href="http://ctan.org/pkg/ibycus-babel">ibycus</a>). Greek script is also
supported by the Unicode-based font encodings PU (<cite>PDF Unicode</cite> used by

<p>Mathematical notation distinguishes variant shapes for pi, phi, rho, theta
(small and capital), beta, and kappa (characters for the latter three
symbols are not included in TeX’s math fonts). These variations have no
syntactic meaning in Greek text and are not given code-points in the LGR
encoding. Greek text fonts use the shape variants interchangeabely.</p>
<p>However, as Unicode defines separate code points for the symbol variants, we
provide fallback LICR macros with detailed error reporting:</p>

<p>T3 also defines some greek letters as well as Latin characters with Greek
names:</p>
<p>According to the Unicode standard, the following IPA characters are identic
to the Greek letters:</p>
<ul class="simple">
<li><p>03B2 greek small letter beta</p></li>
<li><p>03B8 greek small letter theta</p></li>
<li><p>03BB greek small letter lamda</p></li>
<li><p>03C7 greek small letter chi</p></li>
</ul>
<p>The following characters in the IPA block refer to Greek letters:</p>
<ul class="simple">
<li><p>0251  LATIN SMALL LETTER ALPHA → greek small letter alpha - 03B1</p></li>
<li><p>025B  LATIN SMALL LETTER OPEN E = epsilon → greek small letter epsilon - 03B5</p></li>
<li><p>0263  LATIN SMALL LETTER GAMMA → greek small letter gamma - 03B3</p></li>
<li><p>0269  LATIN SMALL LETTER IOTA  → greek small letter iota - 03B9</p></li>
<li><p>0278  LATIN SMALL LETTER PHI → greek small letter phi - 03C6</p></li>
<li><p>028A  LATIN SMALL LETTER UPSILON  → greek small letter upsilon - 03C5</p></li>
</ul>
<p><cite>tipa</cite> uses the macro names <span class="docutils literal">\textepsilon</span>, <span class="docutils literal">\textgamma</span>, <span class="docutils literal">\textiota</span>,
<span class="docutils literal">\textphi</span>, and <span class="docutils literal">\textupsilon</span> for the Latin characters. This is no
problem with 8-bit fonts (set the font encoding to T3 vs. LGR to
disambiguate), but leads to ambiguity with Unicode fonts. <a class="reference external" href="http://ctan.org/pkg/xunicode">xunicode</a> uses the
<span class="docutils literal">gr</span> infix and alias names to disambiguate:</p>
<ul class="simple">

<li><p>03B9 <span class="docutils literal">\textgriota</span></p></li>
<li><p>03C6 <span class="docutils literal">\textgrphi</span> (see x0278 )</p></li>
</ul>
<p>but not for epsilon and upsilon (03C2 <span class="docutils literal">\textgrsigma</span> is the final sigma).</p>
<p>It also assigns alias names to the Latin counterparts, however not on a
systematical basis:</p>
<ul class="simple">

<p>The characters at position 16 and 17 are used in the <span class="docutils literal">\nexus</span> macro

<p>16–MODIFIER LETTER LOW ACUTE ACCENT
17–MODIFIER LETTER LOW GRAVE ACCENT</p>

<p>but according to the documentation of Werner Lemberg’s <a class="reference external" href="http://www.eutypon.gr/eutypon/pdf/e2008-20/e20-a03.pdf">babel patch</a>,
they rather represent the left and right part of U+23E0 TOP TORTOISE

<p>Babel’s <span class="docutils literal">lgrenc.def</span> has some definitions to prevent surprises with
macros that expect a Latin script. These definitions are problematic in a

<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 <span class="docutils literal">\</span>).</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 <span class="docutils literal">\&#64;tabacckludge</span> 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>

the Unicode name with the prefix “acc” (cf. <cite>How to name accent macros?</cite>
in the <a class="reference external" href="README.html">README</a>) reducing the probability of incompatibilities compared to the
two-letter <a class="reference external" href="http://ctan.org/pkg/teubner">teubner</a> diacritic macros or the “text” prefix used by <a class="reference external" href="http://ctan.org/pkg/unicode">ucs</a>.</p>

<p>The diaytika should also always be used in all-uppercase words (even

<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>
