Well, I think SMTP was very successful in getting to 8-bits everywhere. Or almost everywhere. Today ESMTP is the predominant protocol for email exchange. And this was really not in the cards when we designed the MIME stuff. The predominant policy at those times was "use 7-bit generally, and 8-bit locally", the so-called "enclave" model. I was amongst the most vocal proponents af a general 8-bit email exchange protocol, the one that emerged as ESMTP. I remember being at IETF in Santa Fé 1992-ish, where we discussed this, and I was the only European around when it was asked if somebody, especially from Europe, really wanted a general 8-bit exchange protocol. And I raised my voice and insisted. So it was not really questioned anymore and ESMTP was produced. But mostly as a courtesy to the Europeans. Sometimes you can make a difference:-) I think getting to >8bit is a non-starter, as per IESG policies that promotes utf-8 as the primary encoding in protocols. And I really do not see why we should open up to a myriad of charsets (being the author of rfc 1345 I need to stress that:-) We have one, we can deal with two, not many. What we have now is a restricted ASCII for DNS, and we want to go to a restricted utf-8. And nothing else. And we want the backwards compatibility and operation between ascii and utf-8 so we can ensure a happy migration and coexistance. Best regards Keld
