Hi Behdad, I'm using the test data mentioned earlier: http://silpa.org.in/pub/tests/hb/ml/ml-harfbuzz-testdata.txt Test case 11 : 'ഗ്ദ്ധ്രോ' (U+0D17, U+0D26, U+0D27, U+0D30, U+0D13) and much simpler ones like test case 24: 'ത്തെ' (U+0D24, U+0D24, U+0D0E) can be used. Fonts used were RaghuMalayalam, Rachana and Meera (they are available here: http://download.savannah.gnu.org/releases/smc/fonts/malayalam-fonts-5.0.1/) > > Cheers, > behdad -- Cheers, Rajeesh http://rajeeshknambiar.wordpress.com _______________________________________________ HarfBuzz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/harfbuzz
