/**
 * Same as the standard UNIX routine iconv(), but
 * may be implemented via libiconv on UNIX flavors that lack
 * a native implementation.
 *
 * GLib provides g_convert() and g_locale_to_utf8() which are likely
 * more convenient than the raw iconv wrappers.
 *
 * Note that the behaviour of iconv() for characters which are valid in the
 * input character set, but which have no representation in the output character
 * set, is implementation defined. This function may return success (with a
 * positive number of non-reversible conversions as replacement characters were
 * used), or it may return -1 and set an error such as %EILSEQ, in such a
 * situation.
 *
 * Params:
 *     inbuf = bytes to convert
 *     outbuf = converted output bytes
 *
 * Returns: count of non-reversible conversions, or -1 on error
