(RFC5987 uses %XX and UTF-8)

BCP137 doesn't really say anything about that, except a mild scorn for
UTF8 in general in preference for 'human readable' unicode points, and
I unless we want to incorporate RFC5987 into header-structure, we should
probably lean more on BCP137.

I asked previously if header-structure should incorporate RFC5987,
but I understodd the answer as "don't bother" ?

(The main problem in absorbing RFC5987 is that a trailing '*' on a
dictionary key gets a special meaning, and '*' is a valid character
in a RFC7230::token on which I based header-structure's identifier.)

Never attribute to malice what can adequately be explained by incompetence.
