<hr><a name="_details"></a><h2>Detailed Description</h2>
<code>XMLTranscoder</code> is for transcoding non-local code page encodings, i.e.
<p>
named encodings. These are used internally by the scanner to internalize raw XML into the internal Unicode format, and by writer classes to convert that internal Unicode format (which comes out of the parser) back out to a format that the receiving client code wants to use.
