Reading german umlaute from xml file

[Freimann, Mario]

Dear mailing list users,

I have a xml file I want to process with xerces. I now have a problem with 
german umlaute. I extracted the code I use to show the problem. After reading 
the mailing list I switched from XMLString::transcode to a utf8 transcoder, but 
it doesn't work either. The problematic platform is Red Hat Enterprise Linux (3 
32Bit and 5 64Bit). The XMLString transcode works well on a Solaris 10 
platform, the transcoder doesn't work, too. Xerces version is 2.7 linked 
statically.


I don't know where the problem with the transcoder is, any help is appreciated.
