Nope, first time got to know this. While testing i found from given In the given string \u0cab\u0ccd\u0c9f\u0ccd \u0cb8\u0ccd\u0ca8\u0cbe (???????? ) is the actually syllable causing problem. This is very complex and rare combination, it involves CHCHCHCM (4 consonant and 3, C = consonant H = Halant and M = Matra). As far as i know this is max allowed syllable for Brahmi based script though Open Type rules not specifies it. Still i am ok with fixing it, let me know how it should render exactly. Anyone has any more information about such other combination?

The word you have mentioned is a transliterated word from English. So in order to get good readability, it is better to use a zero-width non joiner (u0ccd) after the second consonant. Also, in comparison with Gubbi and Navilu, Lohit doesn't handle the cluster that good. This has been already reported by Shriramana Sharma: https://bugzilla.redhat.com/show_bug.cgi?id=825081 By the way, in the image attached, you have added a space after the second 0ccd!

It is complete now. Lohit web fonts (.woff and .eot) are available for download from [1] Tarball name following syntax lohit--web-.tar.gz Example: lohit-assamese-web-2.5.3.tar.gz I did basic testing with http://pravins.fedorapeople.org/web-fonts/sample-text-woff.html. Looking forward to see more comments from community of Lohit users. We are using http://code.google.com/p/sfntly/ tool for generating .woff and .eot. Thanks to Santhosh for pointing to it. Special thanks to Parag for Makefile :) Let me know if any problem in using web formats or improvement possible. Best Regards, Pravin Satpute 1. https://fedorahosted.org/lohit/
