(The changes that I made in nntp.el has been archived in
<URL:http://article.gmane.org/gmane.emacs.gnus.commits/5519>.)

What I observed was different. The group name "テスト" is
encoded by utf-8 by the nntp server into:
"\343\203\206\343\202\271\343\203\210"
After it is transferred to Gnus, in the nntp process bufer it is
modified into:
"\343\203XY\343\203\210"
Where X is (make-char 'greek-iso8859-7 99)
and Y is (make-char 'latin-iso8859-2 57).
Since Gnus treats a group name as a unibyte string, finally it
is made into:
"\343\203\343\271\343\203\210"

But the modern Emacsen does do so, doesn't it?
