Well, that's an orthogonal discussion. It hasn't been UTF-8 in the past, 
and APIs assume otherwise, so it's not that simple. But it's certainly 
something we can consider in the future.

FWIW, I tried to better explain this in 
<https://github.com/httpwg/http-extensions/commit/5ec7eed4fa2c941a34e868117ef2fb634d8d506e>.

(We discussed this a bit in Stockholm, and my proposal was just to 
opt-in using a BOM in the first bytes of the field value...).

I agree that we need a better solution than RFC 5987.

However, the purpose of 5987bis is just to update a specification that's 
already in use.
