Hi, If you go through archives, it will become clear that Harfbuzz is in active development towards unifying the rendering on free software platform. I too have noticed a specific regression in Pango due to Harfbuzz updates. <a href="https://bugzilla.gnome.org/show_bug.cgi?id=627016">https://bugzilla.gnome.org/show_bug.cgi?id=627016</a> Cheers Arjun <div class="gmail_quote">On Wed, Aug 18, 2010 at 4:20 PM, <a href="mailto:pravin.d.s@gmail.com" target="_blank">pravin.d.s@gmail.com</a> <<a href="mailto:pravin.d.s@gmail.com" target="_blank">pravin.d.s@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hi, I recently while testing found that lohit oriya halant combination's not working properly with qt-4.6.3-8, but previously it was working properly. so i thought might be there are some problem in harfbuzz, but when i changes font to samyak telugu everything works properly. I thought might be we did some thing wrong in lohit long time back and notices now after harfbuzz modification, so tested lohit oriya on windows also but its works well in windows, icu and pango as well. I am presently confuse where should i fix this, in fonts or should check harfbuzz for possible problems Lohit Oriya is available from <a href="https://fedorahosted.org/lohit/" target="_blank">https://fedorahosted.org/lohit/</a> Samyak Oriya is available from <a href="http://sarovar.org/projects/samyak/" target="_blank">http://sarovar.org/projects/samyak/</a> Thanks, Pravin S _______________________________________________ HarfBuzz mailing list <a href="mailto:HarfBuzz@lists.freedesktop.org" target="_blank">HarfBuzz@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/harfbuzz" target="_blank">http://lists.freedesktop.org/mailman/listinfo/harfbuzz</a> </blockquote></div>
