Hi Konstantin,

I applied the patches for thai font rendering from
https://bugreports.qt.io/browse/QTBUG-21206. But the issue I mentioned
in my first email still exist. If src/3rdpart/hafbuzz is used bt Qt
from where are the functions in harbuzz-thai.c called? I see those are
statically linked to libQtCore.so

Does Qt uses the freetype libraries (libfreetype.so). If yes can I
build freetype --with-harbuzz so that Qt will use harfbuzz-0.9.38. Is
this a correct way?
