Question

We are trying to use FFmpeg draw text to support Hindi fonts. but some characters are not rendering properly.

Used Hindi Language Font file :-https://fonts.google.com/specimen/Khula

Input string :- **जिन्दगी सिर्फ हकीक़त है हकीक़त समझो,**

But output renders as output of code

I want some perfect solution to apply assets font on FFmpeg.

Thank you in Advance.
