Is this definition part of Unicode? I thought the use of General Category to answer questions like "this sequence is a word" or "this string is alphabetic" was much more complex than that. (I'm not even sure what the latter means, for any script with any sort of combining mark.)

The effects of virama that spring to mind are:

(a) Causing one or both letters on either side to change or combine to
indicate combination;

(b) Appearing as a mark only if it does not affect one of the letters
on either side;

(c) Causing a left matra to appear on the left of the sequence of
consonants joined by a sequence of non-visible viramas.

Most of these don't apply to Tamil, of course.
