Would it make sense to introduce a `mm-group-coding-system-alist'
(similar to `gnus-group-posting-charset-alist', cf. (info
"(gnus)Charsets")) which takes precedence over the entries in
`mm-coding-system-priorities'.

Example:

(setq mm-coding-system-priorities '(iso-8859-1 iso-2022-jp utf-8))
(setq mm-group-coding-system-alist '(("not-japanese" utf-8)))

(let ((mm-coding-system-priorities
       ;; entry from `mm-group-coding-system-alist' if non-nil -> utf-8
       (push 'utf-8 mm-coding-system-priorities)))
  do-stuff)

What do people think?

Bye, Reiner.
