convert characters between foreign encodings and Unicode (UTF-16). </p>

<section><title>Architecture</title> <p>The Character Conversion Framework

comprises two components: </p> <ul>

<li id="GUID-BD14B058-9F17-5B43-B3B4-12298700A6C2"><p>The Character Encoding

and Conversion Framework component is also referred to as Charconv Framework.

It contains built-in converters for many languages. It also provides APIs

for selecting built-in or plug-in converters. </p> </li>
