A convenience class which handles conversions between MIME charset names and Java encoding names.

   <source lang="java">

import java.util.*; /**

* MIME2Java is a convenience class which handles conversions between MIME charset names
* and Java encoding names.
*

The supported XML encodings are the intersection of XML-supported code sets and those * supported in JDK 1.1. * <p>MIME charset names are used on xmlEncoding parameters to methods such * as TXDocument#setEncoding and DTD#setEncoding. * <p>Java encoding names are used on encoding parameters to * methods such as TXDocument#printWithFormat and DTD#printExternal. * <P> *
