Myanmar Extended-A is a Unicode block containing Myanmar characters for writing the Khamti Shan and Aiton languages.

Block

The block has eleven variation sequences defined for standardized variants.[3] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote the dotted letters used for the Khamti, Aiton, and Phake languages.[4] (Note that this is font dependent. For example, the Padauk font supports some of the dotted forms.)
