- * Utility class for working with character sets. It is somewhat similar to

- * more aliases and is compatible with Java 1.3. It will use a simple detection
- * mechanism to detect what character sets the current VM supports. This will
- * be a sub-set of the character sets listed in the
- * <a href="http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html">

- * <p>
- * The <a href="http://www.iana.org/assignments/character-sets">

- * MIME character set names and to get a list of known aliases.
