--- Comment #1 from Aric Stewart aric@codeweavers.com 2012-07-17 07:27:05 CDT --- I have done the bulk the groundwork here. Now I have to implement GPOS formats and tweak things so they are completely correct.
I believe that with the MarkToBase format most of the Matras should be positioned correctly.
Try retesting.
thanks! -aric
