--- Comment #4 from Pravin Satpute psatpute@redhat.com 2009-12-04 04:04:10 EDT --- dont know which version of meera fonts included in ttf-indic-fonts_0.5.6, but when i installed fonts from there tarball its working properly on fedora 12 as well.

We are using http://mirrors.igsobe.com/nongnu/smc/fonts/malayalam-fonts-04.2.zip in fedora, which is latest upstream version.

can you check which version of malayalam-fonts ttf-indic-fonts_0.5.6 uses, so we can add that in upstream and update package

...

Proposed Solution in ttf

We added 4 rules

blwf: xx l3 -> l4

This rule will make the l4 glyph appear below any Consonant/Conjunct followed by xx l3(eg. ഡ്ല, യ്ല, റ്റ്ല etc.) and it will go against traditional orthography. Which means more contextual rules.

...

ccmp: s1p1 -> s1 xx p1 calt: s1p1 xx l3 -> s1p1 l4 (blwf) calt: s1p1 l4 -> s1 xx p1 l4 (ccmp)

This works for Pango and should also work on Uniscribe, but not on ICU and QT(Harfbuzz).

--- Comment #14 from Harshula Jayasuriya harshula@redhat.com 2011-10-17 22:50:25 EDT --- Hi All,

Pango, Harfbuzz and Windows layout engine all appear to support CCMP for Indic. However, ICU still does not. The ICU developers are under the incorrect assumption that the Windows layout engine does not support CCMP for Indic.

So, in terms of CCMP support for Indic, it looks like we just need ICU fixed: http://bugs.icu-project.org/trac/ticket/7601
