ordinal not in range(128)

[Ralf Claus]

Hello,
can you tell me something about this error ?
With py 1.5.2 and Tcl/Tk 8.05 there are no problems!
With py 2.0 and Tcl/Tk 8.3 this error occurs if i try to
work with german "Umlaute" >äöü< in a Text Widget.
To type s='ö' in the idle is not possible.
How can i solve this problem ?

Gruß
Ralf
