<hr><a name="_details"></a><h2>Detailed Description</h2>
A PangoCoverage C++ wrapper class.
<p>
It is often necessary in <a class="el" href="namespaceGFC_1_1Pango.html">Pango</a> to determine if a particular font can represent a particular character, and also how well it can represent that character. The <a class="el" href="classGFC_1_1Pango_1_1Coverage.html">Coverage</a> object is used to represent that information.
