Err, the other way around

SCM_API char *scm_to_locale_string (SCM str);
SCM_API char *scm_to_locale_stringn (SCM str, size_t *lenp);
SCM_API size_t scm_to_locale_stringbuf (SCM str, char *buf, size_t
                                        max_len);

Granted they all return a fresh string (or store a copy into a
preallocated buffer), but this allows the internal Guile string
representation to be fancier than a byte array if needed by hiding the
internal representation. This will be important when Guile supports
things like Unicode (e.g. like SBCL does by using UCS-32 internally
and converting into an external encoding such as UTF-8 when needed so
as to preserve O(1) string operations and still work with the outside
world).
