OK.  I see a couple of ways to fix it:

1. gnus-default-charset's default value is deduced from the language
   environment:

      (defcustom gnus-default-charset (mm-guess-mime-charset)

   I don't think this is necessarily a good idea.  

   Just because you're using UTF-8, mac-roman, EBCDIC or whatever on
   your local system doesn't mean that it's a good guess that you'll
   receive mail and news using this charset.  

   So maybe `mm-guess-mime-charset' shouldn't choose some charsets --
   UTF-8, UTF-16 and mac-roman would probably be likely candidates to
   exclude.

2. We could add more entries to `gnus-group-charset-alist'.
