Hi Behdad, Thanks for replying.
Few more questions, 1. harbuzz-ng is from http://www.freedesktop.org/software/harfbuzz/release/. Is that correct? 2. So when you say use Qt with harbuzz it means it is not using the harfbuzz in qt-everywhere-opensource-src-4.7.4/src/3rdparty/harfbuzz/src/ and it should use from http://www.freedesktop.org/software/harfbuzz/release/. 3. Qt uses the freetype font engine to render font and harfbuzz is required by freetype to take care of glyph positioning. Is my understanding correct? If yes, then if I update freetype and harfbuzz to latest version then it should solve this issue. Thanks & Regards, Vignesh.
