Hi all,

I have some problems with converting these silly german characters Ä, Ö and Ü
to AE, OE and UE.
I tried to convert them using the change()-procedure as the follong example shows:
  owa_pattern.change( temp, 'Ä', 'AE' ); But this doesn't work because change() doesn't recognize an "Ä" in the string "temp".
Anyone out there who can help me?

Ansgar

BTW: The I/O-string "temp" gets its value via CGI using POST method.
