Description Sayamindu Dasgupta 2007-04-08 20:35:58 UTC 
The sequence <consonant> <ZWNJ> <halant> <consonant> <pre-base matra> should be rendered as <consonant> <halant> <pre-base matra> <consonant>. However, the current implementation in Pango renders it as <pre-base matra> <consonant> <halant> <consonant> which is not correct.

Argghh... replace each instance of  <consonant> <ZWNJ> <halant> <consonant> <pre-base matra> with  <consonant> <halant>  <ZWNJ> <consonant> <pre-base matra>. I'm so clumsy :-(
