problems with unicode

[Amr Hassan]

trying to read unicode tags as the following:

    TagLib::FileRef f = TagLib::FileRef(filePath);
   
    QString artist = TStringToQString(f.tag()->artist());
    QString title = TStringToQString(f.tag()->title());

when i read a char like* Æ, it reads it as ?
why?
i'm viewing the readout on a qwidget
