Question: What if there is no previous native offset, for example when
I call this function from the start of the text?

Proposal: Return -1, similar to previous32() when you "run into the
wall". (Although this returns native indexes while previous32()
returns UChar32s. It still seems reasonable to return a no-index value
similar to previous32() returning a no-code point value.)

I also forgot to give a deadline for the proposal. Please reply by
next Monday, apr24.
