Cyc_utf8_validate_stream() uint32_t Cyc_utf8_validate_stream ( uint32_t *  state, char *  str, size_t  len  ) Use this when validating from a stream, as it may be that the stream stopped in the middle of a codepoint, hence state passed in as an arg, so it can be tested in a loop and also after the loop has finished.
