Hi Andreas,

I have bad news for you. I wrote a bit of code here and already
submitted it to CVS. This code uses Xutf8TextListToTextProperty, an
XFree86 extension, to set the window title as an UTF8 string. Now this
extension wont be present on your Solaris machine, that's why it is bad
news for you. The behaviour of GNUstep will be alright for the rest of us.
What can you do now? First check your GNUstep default String encoding.
This currently gets used for the conversion of the window title and it
does not seem to match what your window manager supports.
Second you could have a go at implementing an alternate way of setting
the window title with either Xmb or Xwc. I would have tried myself, but
I never did get my head around these concepts.

Cheers
Fred
