IIRC, cp1252 is no valid mime-charset.  You can let Gnus treat it like
windows-1252.  Probably your XEmacs doesn't know windows-1252, so you
may be more lucky with iso-8859-1.

The following mapping works in Emacs:

;; cp1252 is no valid mime-charset, but it's used in the wild (should be
;; windows-1252).  Let's treat it as windows-1252 or iso-8859-1.
(unless (mm-coding-system-p 'cp1252)
  (if (mm-coding-system-p 'windows-1252)
      (add-to-list 'mm-charset-synonym-alist '(cp1252 . windows-1252))
    (add-to-list 'mm-charset-synonym-alist '(cp1252 . iso-8859-1))))

BTW, is this a silly virus waring by a broken mailer?

I don't know about vm, maybe they have a similar charset mapping by
default.

Bye, Reiner.
