Font Issue

Hi
I am Designing a Set for a Sports Broadcast, where the official language used Is Tamil(India) I have Imported Tamil fonts into the project but, when used in User Interface it does not work properly, I have tried every bit of settings but the problem with font characters remains same. can someone help

I have even tried some text assets from the marketplace, and they are not 100 % accurate. So, I built the fonts in Maya. Good luck
