*Group* バッファなどでグループ名が化けてしまったのですが、
グループ名はエンコードせずに emacs の内部コードで持っているのに対し、
gnus-group-name-charset-group-alist がデフォルトのままだと utf-8 で
デコードしてしまうためでした。

ということで、以下のような設定をすると正常に動作しました。
(add-to-list 'gnus-group-name-charset-group-alist '("nnshimbun" . nil))


しかしながら、nnrss のようにグループ名を utf-8 でエンコードして持つという
手もあるのですが、どちらが良いでしょうか?
添付のような変更で、gnus-group-name-charset-group-alist がデフォルトの
ままで表示できることは確認しています。
