As fas as I know, there is a big trouble with Indian fonts (like Devanagari) in Android. So I think of using IAST to avoid using Devanagari. But there are some letters with bottom dots (like ṃ or ḥ). They are unicode, I guess, because every text editor shows them easily. But my text view doesn't. What should I do?
Update: The solution is to use DejaVu fonts or any other set of fonts with full UNICODE support.
