I don't think nl_langinfo(CODESET) is portable--as far as I can tell,
there's no standard for either the codeset names returned by
nl_langinfo, or the acceptable codesets for iconv. I ran into a
problem with an older version of scmxx (see
NetBSD's nl_langinfo(CODESET) would return "646" for ASCII and
"ISO8859-1" for ISO 8859-1. However, GNU iconv was looking for
"ASCII" or "ISO646-US" for ASCII, and "ISO-8859-1" for ISO 8859-1.
