To summarize anon719148’s link, you cannot use Burmese numerals as verse markers in Paratext. Paratext will only recognize the western numbers 1, 2, 3, 4, 5, 6, 7, 8 ,9 and 0 as verse numbers (or as chapter numbers). If you want to display the Burmese numbers you can enter them after a \vp marker, but this is for display only. When you are at the point of publishing your text, there are ways the typesetter could replace the western numbers Paratext needs with the Burmese numbers.
