Bengali lacks the letter for /va/. Assamese ৱ has been used to represent /va/. Also, the equivlent letter for the Tamil/Malayalam ழ has been created by placing the nukta on /sha/ ষ

Oriya

Sinhala

Sinhala traditionally uses the short vowel /e/ and /o/ to denote long /e/ and /o/ in Sanskrit/Pali texts. The long vowels are used only in Sinhala text.

Tamil

Tamil publishers generally use a system of superscript/subscript numerals to denote the Sanskrit Varga consonants which the Tamil-Script lacks. The same is used here. Just the characters for R, RR, L, LL, Anusvara & Chandrabindu.

Grantha

Grantha traditionally lacks a Nukta.  It is proposed as a new addendum to the Script.

Tamil-Grantha

It is a hybrid between Tamil-Grantha script used by some publishers in Tamil Nadu to print Sanskrit texts.

Telugu

Telugu Letter ఁ though named as Chandrabindu in Unicode, is not the real Chandrabindu. It is called Arasunna, and is a prosodical character. There are some modern texs use this character as the equivalent of Chandrabindu when writing Hindi in Telugu Script. I have for now used this character as the equivalent for Chandrabindu. There real Chandrabindu is in pipeline for inclusion in Unicode (along with Malayalam and Kannada Chandrabindu-s )

Thai

The symbol for Visarga as mutated to a vowel sign for short a (Sara a). I have just shown the Visarga using a colon (:)
