Problem with accented characters

[gt.beta2]

Hi
Whi is this line ...

modelo->setHeaderData(Produtos_descricao, Qt::Horizontal, tr("Descrição"));

modelo->setHeaderData(Produtos_descricao, Qt::Horizontal, tr("Descrição"));

To copy to clipboard, switch view to plain text mode 

... not showing the accented characters correctly in the view that i created?

Is it a Qt or a Operating System issue?

Thanks
