Right, it would be more desirable to use UTF-8 internally, rather than
doing ad-hoc encoding translation everywhere.

Currently the encode/decode functions in message.el works fine for
GBK, this bug would not affect people who are only using Gnus for
IMAP/Maildir.  It would still better leaving these two systems (News
and Messages) separated. Today most email services are already
switched to UTF-8. It's only that many NNTP servers are still using
the old encoding for legacy reasons.
