public final class UTF8Decoder
extends B2CConverter

Moved from ByteChunk - code to convert from UTF8 bytes to chars. Not used in the current tomcat3.3 : the performance gain is not very big if the String is created, only if we avoid that and work only on char[]. Until than, it's better to be safe. ( I tested this code with 2 and 3 bytes chars, and it works fine in xerces ) Cut from xerces' UTF8Reader.copyMultiByteCharData()
