I see that there is support for CJK. I would like to add support for Indic characters. I have a font that supports it. Is it safe to replace the i18n.ttf with that one? Or is there a font that supports all the unicode characters that can be installed in Kindle 3 WIFI (FW : 3.0.3)? I am in particular looking for support for Tamil Character set (an Indic language).
Also I havent JB'ed my kindle. Is it safe to do so (not expecting the usual disclaimers

but just an opinion based on experience)? Is it easy to recover if I accidentally bricked the Kindle?
thanks,
Murali
