Hmm, `scm_c_{read,write} ()' are biased toward binary data, according to
the manual and to their prototype (they take `void *' buffers). So I
would keep them this way.
`scm_puts ()' is more of a concern since it takes a `char *', which the
caller may consider an 8-bit-encoded, null-terminated string. We should
probably deprecate it, and have it return an ISO-8859-1 string,
transcoding as necessary.
And `scm_gets ()' doesn't exist actually. ;-)

OK.
Thanks,
