Notes 1.^ As of Unicode version 17.0

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