Emacs does not seem to correctly handle UTF-8-Based Percent-Encoding as
illustrated in Chapter 6.2 from RFC6068.
The command
emacs -Q -l browse-url -eval '(browse-url-mail "mailto:user@example.org?subject=caf%C3%A9&body=caf%C3%A9")'
should result in a message buffer with the string "café" insterted into the
body part of the message. Instead the string "café" is inserted.
I am running Ubuntu 18.04.3 LTS.
M-x emacs-version returns:
"GNU Emacs 26.3 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.22.30) of 2019-09-16"

Yes, the assumption in rfc2368-unhexify-string is that percent
escaping is being done of ASCII characters.
epg--decode-percent-escape-as-utf-8 in epg.el does the
right thing, it could be renamed and moved. I think rfc2047 decoding
needs doing on the result as well. Lars, should I just stick these in
rfc2368.el but named something like rfc6068-unhexify-string and
rfc6068-decode-2047-string or something?

Oh, and thereʼs another version in gnus-util, and one in url, and an
almost compatible one in org [1]. The gnus and url ones suffer from
this same issue, although they both return different wrong results :-)
At least the epg, rfc2368, gnus, and the url versions look like they
can be unified. Not sure where to put them though.
Footnotes:
[1] It supports % representation of the UTF-8 encoding of chars, but
also of the unicode code point of chars, so eg %E1 gets turned
into á. Iʼm sure thereʼs some historical reason for that.

Putting them in either rfc2368 or url.el would make sense. Hm...
perhaps url-util.el?

I am assuming this bug is not yet fixed. Can anyone advice on a
workaround I can apply for this bug. I am using emacs 26.1 (as packaged
in Debian buster)

I made a new file, obsoleted rfc2368, and adjusted browse-url and epg.
So the original reported problem should now be fixed in Emacs 28.
