Hi Konstantin,

Thanks for your reply.

Unfortunately I'm stuck with Qt 4.7.4

I checked this thai font issue on a board with Qt 4.7.4 libs and this
happens with one particular font DejaVuSans.ttf.
When I tried DejaVuSansCondensed.ttf font the issue is not seen. I
wonder any of the harfbuzz-thai calls are not invoked for DejaVuSans

Does font make a difference in harfbuzz bundled code
(src/3rdpart/hafbuzz) in Qt.

Is there a way to trace harfbuzz-thai.c function calls for eg thaiWordBreaks.
