Incorrect glyphs with the Graecall font

The QPainter::drawText() does not display correctly some characters using the font "GraecaII".

ALL characters higher than 128 are replaced with other characters. Enclosed there are two images: the first one shows the correct layout of GraecaII font, the second one shows a QT Window that uses the following code to
display all the characters with negative advances and the complete map.
