I don't think Unicode is the problem.  Shiro's proposal is well thought
out, handles encoding simply, and is based on real working practice in
Gauche.

The main complication is that Scheme strings don't necessarily have
anything to do with C strings.  Shared substrings, in fact, are not C
strings as already acknowledged by the API and strings as lists or Boehm
cords aren't even consecutive memory references.  Handle these issues
and the only thing left for Unicode is to specify the default encoding
(and an advanced SRFI could specify fetching w/ alternate encodings for
efficiency).
