This is an ugly IDLE-"feature". IDLE uses (and allows) only characters 
with ASCII-code < 128
As the error-message says, Umlaute hav ASCII-codes not in this range:

 >>> map(ord,"äöüÄÖÜß")
[228, 246, 252, 196, 214, 220, 223]
 >>>

You may change this by informing IDLE/Python about your local environment.
To this end put the attached file

sitecustomize.py

into the Lib-subdirectory of your Python-Directory (standard: 
C:\Python22\Lib).
Restart IDLE and the problem will be disappeared.

If there could arise other new problems because of  changing the "locale"
(see global module-Index, locale.py) I don't know. I didn't encounter  any.

Best wishes
Gregor
