Tamil font error in FCPX

Hi, i have tried to write a tamil text in FCPX 10.0.4 with Anjal text which is comes with mac is works fine for me. But i got error when i use third party tamil fonts. It cant paste the same tamil script what i have copied from anjal font. Is there any Tamil font available from Mac other than Anjal font for FCPX or is there any other way to resolve this issue...Need your help. Thanks....
