These were the syllables where I had problems using Tise:
It should be noted that 'dh' or 'gh' are supported by Tise in the beginning of a string, but not in the middle.
In case of lash/, the slash refers to a virama sign which is not properly rendered by all Unicode fonts that I tested.
In case of r+ya(?), I am not certain about the correct EWTS spelling.
Further development of Tise depends very on users feedback, and
comments are most welcome. Please send the syllables that don't work
well to this list. If some EWTS syllables don't work, it is a serious
bug and I will try to fix it quickly.
Devanagari enhancements will be possible if and when my time allows.
