QPainter::drawText() doesn't render unicode correctly on macOS

Calling:

painter->drawText( rect(), Qt::AlignCenter, "üöäßüöäß" );

From inside QGraphicsObject::paint() on macOS 11.0 doesn't render it correctly. See attached.

Doesn't seem to depend on the font.

Works fine on Windows with Qt 5.12.7.

Not sure if this is related to QTBUG-28853 .
