Type the unicode combination given for each. Actual results: Does not combine to form the conjunct and does not show the proper shape also.

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.
Patch submitted on #206281 (attachment id=137331) is applicable for this bug as well.
Bug for this issue is also filed in gnome bugzilla against pango. Patch is also attached. 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.
