Yeah, this has been discussed before.  Database and user names both
have this affliction.

I don't see any very nice solution at the moment.  Once we get support
for per-column locales, it might be possible to declare that the shared
catalogs are always in UTF8 encoding and get the necessary
conversions to happen automatically.
