Editor OT: s-underdot in vim?

[Trevor Bača]

Hi,

Anyone know the magic key combination to produce s-underdot in vim?

I've got a multibyte-compiled vim that I use for all sorts of extended
Unicode, and it works great. But perusing the table generated by

 :digraphs

doesn't turn up any way to produce the lowercase s with underdot (as
is used, for example, to transcribe retroflex ṣ from Sanskrit).

Any clues?
