Thanks for filing this bug and testing X2Go.

Please note that Posix usernames are not allowed by RFC to contain  
accents on characters. Posix usernames should be ASCII only.

Normally, the home directory's basename should be identical to the  
username, thus also contain ASCII-only characters.

I don't think we will provide a fix for the reported bug, as your  
system does not seem to comply to Posix standards.

If you think I am wrong about this, please give feedback.

Thanks,
Mike
