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 (ಫ್ಟ್ಸ್ನಾ ) 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?


Thanks,
