Hi Andreas,

thanks for your mail.

Actually, my standard locale is en_GB.UTF-8. I have tried that now --- 
with partial success.

1. If I paste my German umlauts into the input widget with the mouse, I get:

Warning: Xt:
    Name: xmTextField
    Class: XmTextField
    Character '\344' not supported in font.  Discarded.

Still the "ä"  is  part of the input and the Umlaut shows up correctly 
in the output. In the input window, the Umlaut is not displayed.
 
2. If I try to insert the umlaut with the keyboard (Compose+"+a), I get 
a slightly different behaviour:

Error message is the same and the umlaut character is not displayed. It 
also gets inserted into the input string. Subsequent characters, 
however, are inserted to its left ("Er schläft" yields "Er schlftä"). It 
is possible to fool the system by entering all non-umlauts first, and  
then insert the umlaut.   

I hope that helps narrowing down the problem.

Best wishes,

Berthold
