Could be, I don't know. I'd have to debug into Qt code to find out why the 
local 8 bit codec isn't working. It uses iconv for that.

QFile::encodeName is exactly the encoding issue...

You can do this:
		QCoreApplication app(argc, argv);

That will create and destroy the application. It should be enough to 
initialise Qt.

We can also think of providing a static method like the QFont one you
