Yes, I agree with you and will take your advice.
Thanks for discussing the issue.

For my needs, I will just replace gnus-group-name-decode with:

#+begin_src emacs-lisp
  (defun gnus-recent-decode-utf8 (string &optional charset)
    "Decode a gnus-group name.
  Replaces `gnus-group-name-decode' for decoding group names.
  Default utf-8-emacs CHARSET unless provided otherwise."
    (decode-coding-string string (or charset 'utf-8-emacs) t))
#+end_src


I guess you may close the bug.
