Hi Kumara,

My pleasure. Would you have preferred both notations simultaneously? Such that both 'n and "n became n-overdot? My concern in that case is that it is not a true transliteration as a full round trip is not guaranteed to match the input.
Velthuis(IAST-Unicode(Velthuis('n))) = "n.

Similar to the square of the square root of -2 is +2. :)

Whatever you prefer; I've made it hoping to match your needs.

Cheers,
Alex
