Why unicode fonts are not working for Telugu language in fcp

Hi,
I have Mac Pro cylinder with the latest version of FCPX, I need to use the Telugu language in my editings, but when I tried to use the script changes (mixes one letter with another). But when I google translate something into the Telugu language through safari browser it comes well, even when I copy and paste in Notes it comes well but it doesn't work in FCPX! I have many unicode fonts (http://telugufonts.in/) they all work well in Notes, Word, etc but not in the FCP.

can anyone please help.
