In this patch I use simple casts instead of the costly ucs2_to_ucs4
and ucs4_to_ucs2 functions. It turned out that all display issues are
resolved... including math! It even brings a very nice speed-up...
Here is a cleaned up version of the patch.
[...]
// Qt rbearing is from the right edge of the char's width().
- unsigned short sc = ucs4_to_ucs2(c);
+ QChar sc(static_cast<uint>(c));
return m.width(sc) - m.rightBearing(sc);
Ah! I forgot that one, I will update the patch with:
// Qt rbearing is from the right edge of the char's width().
- unsigned short sc = ucs4_to_ucs2(c);
- return m.width(sc) - m.rightBearing(sc);
+ return m.width(ucs4_to_qchar(c)) - m.rightBearing(sc);
Sorry, wrong again... that would be
- unsigned short sc = ucs4_to_ucs2(c);
+ QChar ucs4_to_qchar(c);
return m.width(sc) - m.rightBearing(sc);
