Increasing the severity of the bug as this is a must have feature for the locale.
Font for bn_IN is used for as_IN as well. The font has the GSUB rule required for vattu form of as_IN letter RA(u09F0). bn_IN letter RA(u09B0) works well in its vattu and reph forms. Pango declares u09B0 as '_rv' and u09F0 as 'ct'. Thus this is a Pango bug. I am changing the comoponant of the bug.
Created attachment 137331 [details] Patch for indic-ot-class-table.c The patch changes the property bit of U09F0 from 'ct' to 'rv'
The patch is at upstream as well: http://bugzilla.gnome.org/show_bug.cgi?id=358174
Thanks for the patch, Rahul, move to Behdad to review and build it into pango.
The present version of Fedora has these bugs solved. I am presently having Fedora 7 rawhide and the renderings are perfect. Also RHEL5 has these problems resolved.
In line: U+09AE U+09CD U+09AD U+09CD U+09F0 mdYd m/B/r When you input mdYd using as_IN inscript, you will not get the correct result.So please change to input "cdYdj", this will be ok.
