Could you try the following patch? [*] It should automatically do the
setup for windows-125[0137] (which are available in Emacs 21).  If no
charset (or alias) is found, it will print a message.  (Displaying as
ASCII is and replacing unknown chars with `?' is not included.  I'm
not sure how this could be achieved in Gnus.)
