Description: declaration: package: org.apache.tomcat.util.buf, class: Utf8Decoder

# Class Utf8Decoder

java.lang.Object
java.nio.charset.CharsetDecoder
org.apache.tomcat.util.buf.Utf8Decoder

public class Utf8Decoder extends 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.
