Thanks for you help. Now I undestand. It's true somehow my terminal
does not handle unicode characters.
After I entered "\encoding latin1" as you suggested everything works
fine. So the answer is that without that unicode characters get
displayed.
But in which encoding? I guess utf8 or utf16...
But why doesn that fail only for äüö? Shouldn't any other letter
encoded in utf16 also fail?
I mean unicode itself is 16 bit long. So "münchen" should expand to 14
characters. But only ü expands to two characters.

No thats ok. Java communicates with psql using unicode only. That's
why it also worked...
