Telugu font rendering broken with Devanagari fonts?

Hi, We are using unity 5 for development. We need to display our regional languages such as Telugu, Hindi in the game scene, but when these language texts are copied in text area its shown re-edited characters and special characters, even we tried to display using the same through script (in script it displaying fine) Searched in unity forums but no help available except some 3rd part font creators like TextMesh Pro. Could you please help us to resolve this issue.

Thank you

unity do not support for that i am trying it from 10 years ago, i think i will die before getting it work for unicode. But if you are using normal hindi font or like so, then you can do it by simply creating font assets.
for unicode character in devnanagari it doesnt work at all

TextMesh Pro has been integrated into the engine for some time now, it’s not third party.
