you should be able to set up a non-utf8 db via the ui

currently we "require" that any database configured be using UTF-8.

however:
1. you can do a backup / restore to a non-UTF-8 db
2. you can manually edit the config.xml and fecru will start up (just with warnings)
3. if you are only using fisheye, this isnt really an issue and shouldnt affect you.

we should make it clear that the database is not UTF-8 when setting it up in the UI, but we should still allow the user to save the settings.
