Actually, it was scm_from_utf8_string, since GUILE_VERSION was 200005

 -- C Function: SCM scm_from_latin1_string (const char *str)
 -- C Function: SCM scm_from_utf8_string (const char *str)
 -- C Function: SCM scm_from_utf32_string (const scm_t_wchar *str)
     Return a scheme string from the null-terminated C string STR,
     which is ISO-8859-1-, UTF-8-, or UTF-32-encoded.  These functions
     should be used to convert hard-coded C string constants into
     Scheme strings.
