I checked Keith Stribley's www.thanlwinsoft.org on the current Unicode implementation for Burmese. I found out that he has done implementation for the new, proposed standard for Myanmar (which is still in the process of being accepted). Here is the converter to that standard. It can also convert Myanmar Unicode 4 to the proposed standard. His website has lots of information about Myanmar Unicode. Padauk has been the greatest Myanmar unicode font with excellent design. The only drawback is it uses Graphite rendering engine and requires a special build of Firefox, OpenOffice to use.
