The mapping procedures string-tabulate and string-unfold return characters.
We should be encouraging people work at the character level - because in a Unicode
world with grapheme clusters and what-not.

The mapping procedures should return strings - or characters, for compatibility.

Probably the same applies to string and make-string - the arguments should be
strings or characters.

It probably makes sense to defer this issue for a successor SRFI.
