I no longer think this is a font issue.  I think it was introduced
in the middle of 2010 with Qt 4.7.  floatWidthForSimpleText was
introduced in r61002.

If I change the call to width() in floatWidthForSimpleText to be
similar to the complex path (floatWidthForComplexText), then this
seems to work.  I would also assume taking the complex path would work
since the 2 routines are almost identical other than the call to
width().

#if 0
    int w = QFontMetrics(font()).width(string, -1, Qt::TextBypassShaping);
#else
    int w  = QFontMetrics(font()).width(string);
#endif

Do you have any advice on how to best correct?  Should we be taking the
complex path for zero-width chars?  Or is there something deeper wrong?
