Sometimes I can get latin1() to work but not always, even using QChar as 
above. Working with the data always(?) works (although its a pretty nasty 
hack on my part) I'd suggest working out what the data structure is and 
dealing with it appropriately. What is the difference with qt2? Hmmm maybe I 
should get qt3 and try it...

At this point Bernd is wondering why we don't use libgdb ... :-)
