That makes things a lot clearer. Thanks.

The Unicode Technical Committee have been persuaded to recant on that
description. (They can't change the name.) Interestingly, there is a
two-dotted Tamil symbol that is used for Sanskrit and Saurashtra in
the Tamil script. It's not in Unicode. For Sanskrit it seems to be
the real visarga - for Saurashtra it seems to perform the same role as
Tamil aytham. Just to confuse matters, the Saurashtra *script* has
yet another symbol for the aytham role!
