`char *' is not a string type. It was simply pressed into service as
one because the C language is too low-level to provide proper handling
for string objects. Scheme has no such trouble; therefore it has
string objects and no direct analogue to `char *'. For example,
null-termination is not an issue in Scheme.

A sensible FFI would provide a way to convert Scheme string types to C
strings for procedures that require them. If you really need
single-byte strings, it shouldn't be hard to write a library for such
in terms of bytevectors.
