Hello,

Qt widdget and QTextEdit failed to render unicode character not contained in the current font.

I add an image to show the problem:
1. I write some japanese characters which aren't in the current font (here MS Shell Dlg 2) without hinting (top image) -> all is ok
2. I select one of the character and I add to the char format fmt.setFontHintingPreference(QFont::PreferNoHinting); -> the character (image bottom) seems to become enorm (height: ~100px x width: > 2000px).

It seems that with no hinting Qt is no more supporting the unicode and I have no workaround to solve mixed unicode text (text which needs more than one font to be drawn) in widget.

I report the problem in Qt 4.8.6 but the problem could be too into Qt 5.x.

Regards,
Bilbon.
