I am definitely not the party to be satisfied here;-)... I only jumped in to remind that the issues of IETF Message Bodies and Message Headers are separate and very different, so that the history of the "just send 8 bits" appeared to perhaps need some refreshment. I think that Keith is talking along the same lines, but beyond what I have said, I am not able to contribute more. I have stopped doing IETF work since the Chicago IETF where I finished my work with MHTML, and no longer had travel support for any more IETF work. And then I also retired, more or less, mostly. So, having had my say for whatever it might have been worth, I would just as soon be omitted from the rest of this discussion.
