You can't set the default encoding. If you could, then scripts that run on your 
machine wouldn't run on mine.

If there's an error, it's the fact that you use a regular string at the 
beginning ("Fächer") and a unicode string later (u"Fächer"). But set objects 
can't know that that's the problem or even if it *is* a problem.
