This question is an exact duplicate of:
I'm trying to get Kannada language support on my phone. I've rooted my Sony Xperia Neo L which is running ICS 4.0.4 and installed Kannada font in system/fonts. The problem is, all the other indic fonts like tamil, bengali, devanagari, hindi are rendering perfectly but not Kannada. I've added the Kannada font in fallback_fonts.xml file. Is that a font problem?
