It seems that you have demonstrated the existence of a large body of deployed software (including, but not limited to, Windows Mail and unmodified INN) that will not work with UTF-8 newsgroup names. That leads me to suggest that if we want to have UTF-8 newsgroup names, perhaps we need to have a capability signallling mechanism and some kind of block/downgrade mechanism (one could imagine simply not distributing or admitting the existence of UTF-8 newsgroups to anyone who does not signal support, or one could imagine more complex schemes.
