After I figured out how to add new fonts, I decided to create a language pack with most major Indic fonts: Bengali (hopefully Lohit-Bengali also contains the additional Assamese characters…let me know), Devanagari, Gujarati, Gurmukhi, Kannada, Malayalm, Odia, Tamil, and Telugu. The fonts used are the Lohit family of fonts.
As I found out, you can install this by downloading the file and opening it with the Pebble app.
Let me know if you run into issues and if something is wrong. I mostly just use the Kannada and Devanagari fonts, so I won’t immediately know if the other languages are broken!
