Version: 4.4.0~beta1 (using Devel) Installed from: Compiled sources Compiler: gcc (GCC) 4.2.3 (Debian 4.2.3-1) OS: Linux These are the cases for which qt does not render Malayalam correctly and a patch is provided 1. traditional script conjuncts with postbase matra 2. Malayalam vattu ra glyph for reformed script 3. chillu + postbase consonant + virama 3. Malayalam SAMVRUTHOKARA Also Malayalam needs to process ZWJ for rendering chillus (pure consonants - combination of consonant + halant + zwj). Pango had a flag SF_PROCESS_ZWJ for this.

Created attachment 24148 [details] patch for 3 cases This patch was prepared by Suresh for qt3. I have ported it to qt4.4/harfbuzz We still need a way to process ZWJ (it was working correctly until 4.3)
