Philippe said some interesting things about the status of
EU recommendations, Directives, etc., but...

This is false. An application exchanging data encoded with GB18030 may
be conforming to the GB18030 standard, but it is not thereby conformant
to ISO/IEC 10646. If it exchanges a LATIN LETTER A WITH ACUTE with
the byte sequence <A8 A2>, then it is indeed conforming to GB18030, but
that is not a conformant representation of LATIN LETTER A WITH ACUTE
in any encoding form for ISO/IEC 10646 (or the Unicode Standard).
You are confusing the possibility of interoperability between GB18030
data (and applications) and Unicode data (and applications) with
the issues of conformance to particular standards.

False. Both GB18030 and ISO/IEC 10646 will be amended in the future,
and mappings will change, and neither has (in principle) a closed repertoire.

False. What appears (in the future) in GB18030 will depend on what
the Chinese standards organization decides to put in it. That is up
to them, as it is their standard, and not an ISO standard.
