Well, you can go around it, but I doubt that it is a problem.

 s:=TStringList.Create;
   s.LoadFromFile(fname);
   w := UTF8Encode(s.Text);
   Dir := GetCurrentDir;
   SetCurrentDir(ExtractFilePath(fname));
   QApplication_setStyleSheet(QApplicationH(QCoreApplication_instance), @w);
   SetCurrentDir(Dir);
   s.Free;
