Not having checked the source I think this line can solve it.

Qapp->setDefaultCodec(QTextCodec::codecForName(getenv("LANG")));

Where the QtextCodec stuff is replaced with whatever codec you actually 
use. I use this in an application and I know I get the desired result and 
before having it it didn't work. Don't really know why it doesn't get the 
codec from LANG itself, but hey. I stick with what works :).
