With advent of qt5 glyphs on codepoints 10, 12, 13 can't be shown anymore.
In this patch we copy the glyph pairs to new codepoints:
dotsint: 19->41 (this one was already moved by Goerg, now moving to the same block)
oint: 11->43
oiint:13->45
I couldn't find fix where both qt4 & qt5 would show correct results,
so this patch fixes qt5 situation, but breaks qt4, which hopefully
won't be needed for master.
Testing and debuging is somewhat tricky, becuse qt sometimes prefer to
load global fonts in /usr/share while ignoring the local git tree.
To be continued in other fonts.
