43  * GLib provides g_convert() and g_locale_to_utf8() which are likely
44  * more convenient than the raw iconv wrappers.
45  *
46  * Note that the behaviour of iconv() for characters which are valid in the
47  * input character set, but which have no representation in the output character
48  * set, is implementation defined. This function may return success (with a
49  * positive number of non-reversible conversions as replacement characters were
50  * used), or it may return -1 and set an error such as %EILSEQ, in such a
51  * situation.
52  *
53  * Params:
54  *     inbuf = bytes to convert
55  *     outbuf = converted output bytes
56  *
57  * Returns: count of non-reversible conversions, or -1 on error
