I'm working with a fairly (make that very) technical manuscript dealing with Hebrew grammar. Along the way, it describes the convention used in the so-called "Pseudo-Ben Naphtali" tradition for distinguishing
sin from
shin, which was a dot
within either side of the letter.
I'm not sure how to manage this, though it may involve a kludge of some kind. Here's what I've got:

shin is fine (that's just a dagesh), but the
sin is nuisance. Any advice? Or should I just "kludge" it?! Thanks for any help with this!
David.
