J8, in contrast, provides a lower case result from hfd. Note that an earlier implementation assumed the j6 implementation of hfd which where hexadecimal letters resulting from hfd were upper case. J does not have a native urldecode (until version 7 when the jhs ide addon includes a jurldecode). While the default is to decode parameters as UTF-8 (which is the W3C recommendation,) the characters may have been encoded in another encoding scheme, and this can be handled correctly.
