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.
