Class UTF8Modified

java.lang.Object
  javaFlacEncoder.UTF8Modified

public class UTF8Modified
extends java.lang.Object

This is a utility class that provides methods to both encode to and decode from the extended version of UTF8 used by the FLAC format. All functions should work with standard UTF8 as well, since this only extends it to handle larger input values.
