[issue2278] [Py30a3] xml.parsers.expat recognizes encoding="utf-8" but not encoding="utf8"

[Benjamin Peterson]

Benjamin Peterson <musiccomposition at gmail.com> added the comment:

Should the parser recognize "utf8"? I looked at the XML standard [1] and
it referred me to the IANA's charts [2]. It appears the the only correct
way to denote UTF-8 is "UTF-8".
