I prefer not to have a header, only negotiation before transfer of data.
If a header is used (there is a problem with a header due to it have to
be before all other headers to simplify message handling), the rules should
be the same as fpr SMTP negotiated UTF-8

You can make negotiation before transfer a REQUIREMENT of some extended SMTP, but SMTP is not the only mail transport protocol around, and you cannot impose such a blanket requirement on _every_ transport protocol, both existing and not yet invented.


That is why you need both the negotiation (for those protocols which you are in a position to specify) AND a header (for those you can't).

Those who write gateways between protocols will just have to do the Right Thing (yes, that may be hard to achieve, but gateways are going to exist whether you like it or not, and yes gateways may well be the weakest link in the chain - so what's new?)
