public class Utf8Decoder
extends java.nio.charset.CharsetDecoder
Decodes bytes to UTF-8. Extracted from Apache Harmony and modified to reject code points from U+D800 to U+DFFF as per
RFC3629. The standard Java decoder does not reject these. It has also been modified to reject code points greater
than U+10FFFF which the standard Java decoder rejects but the harmony one does not.
