I've tried tweaking all kinds of things but the sad truth is that I am really 
pathetic at figuring out libraries when no documentation is given, and I sure 
can't find any documentation.

I see that the fpgui helloworld program handles unicode nicely. I guess I'll try 
and imitate whatever's happening there.

Thanks again, Graeme!
