Hi Thierry,I've just seen the update for the JSON representation. The RFC 4627 (http://tools.ietf.org/html/rfc4627#section-3) says, that "JSON text SHALL be encoded in Unicode. The default encoding is UTF-8". So it is not forbidden to use othe character sets. So I propose to use UTF-8 as default, but do not forbid other character sets.
best regards Stephan
