<h2>Usage</h2>
<p>This file is input by the font encoding definition files <a class="reference external" href="lgrenc.def.html">lgrenc.def</a>. and
<a class="reference external" href="tuenc-greek.def.html">tuenc-greek.def</a>.</p>

<h2>Implementation</h2>
<section id="ensuregreek-greekscript">
<h3>ensuregreek, greekscript</h3>
<p>Provide “empty” encoding-specific definitions for <span class="docutils literal">\ensuregreek</span> and
<span class="docutils literal">\greekscript</span>. The definitions in this file make the font encoding fit
for use with the Greek script. (See <span class="docutils literal">textalpha.sty</span> for default
definitions.)</p>
<p>The <span class="docutils literal">\ensuregreek</span> macro can be used to ensure that its argument is set
in a font encoding with support for Greek. If the active font encoding
supports it, kerning between adjacent command calls (e.g.
<span class="docutils literal"><span class="pre">\ensuregreek{A}\ensuregreek{\Upsilon}</span></span>) is preserved. This allows, e.g.,
wrapping of compound Unicode character definitions.</p>
<pre class="literal-block">\ProvideTextCommand{\ensuregreek}{\LastDeclaredEncoding}[1]{#1}</pre>
<p>The <span class="docutils literal">\greekscript</span> declaration switches to a font encoding supporting
the Greek script, if required. The following definition announces the
<span class="docutils literal">\LastDeclaredEncoding</span> as Greek-supporting:</p>
<pre class="literal-block">\ProvideTextCommand{\greekscript}{\LastDeclaredEncoding}{}</pre>

<section id="aliases">
<h3>Aliases</h3>
<p>Aliases are defined via <cite>DeclareTextCommand</cite> so that up/downcasing works

<h3>Composite diacritics</h3>
<p>Composite accents can be input as sequence of simple diacritics (in
arbitrary order) via named macro, symbol macro and “transcription
characters”, e.g. one of</p>
<pre class="code latex literal-block"><code><span class="keyword">\accdialyticavaria\textalpha</span>,
<span class="keyword">\accdialytica\accvaria\textalpha</span>,
<span class="keyword">\"\'\textalpha</span>,

<span class="keyword">\'</span>"<span class="keyword">\textalpha</span>.</code></pre>
<p>Separate definitions for the supported variants of the second input token
are required as composition is based on the non-expanded input</p>
<p>The composition with simple “transcription characters” must also be defined
for the symbol macros, otherwise it fails with <span class="docutils literal">\Makeuppercase</span>.</p>
<p>For Unicode encodings (where they do not resolve to Greek named macros,
composite definitions starting with standard macros are requried:</p>

<span id="uclclist"></span><h3>UPPERCASE</h3>
<p>If UPPERCASE (all-caps) is generated with <span class="docutils literal">\MakeUppercase</span>, macro
substitutions in the <span class="docutils literal">\@uclclist</span> apply. This can be used to drop the
diacritics (except dialytika and <a class="reference external" href="https://en.wikipedia.org/wiki/Iota_subscript">iota subscript</a>). Different conventions
exist for the <a class="reference external" href="https://opoudjis.net/unicode/unicode_adscript.html">treatment of the iota subscript with uppercase letters</a>. In
the CB Fonts, a small capital adscript iota is used.</p>

<h4>@uclclist extension</h4>
<p>Based on the <a class="reference external" href="http://www.eutypon.gr/eutypon/pdf/e2008-20/e20-a03.pdf">babel patch</a> and <span class="docutils literal">fontenc.sty</span>.</p>
<p>The definition of an auxiliary, self-resetting macro makes this idempotent
(only the first use of this function will expand the <span class="docutils literal">@uclclist</span>).
The second and third lines are TeX’ way of writing <span class="docutils literal">uclclist += …</span>:</p>

<h4>Mark hiatus</h4>
<p>Tonos and dasia mark a hiatus if placed on the
