Hi,
Is that referring to clients and servers still relying
on resourceprep
when the RFC is clear that resource is a PRECIS OpaqueString
Is that supposed to
allow all emojis? If the lib I use says 🎉 is
forbidden, is it because it does resourceprep instead of doing PRECIS? 🚓
(which has almost no limitations other than forbidding
control
characters, which seems sensible for nicknames).
I am not saying we should, but
FWIW discord and telegram (maybe other
networks too) do allow control characters in nicknames.
XEP-0172 MUC support removed in version 1.1 of that
XEP but still used
in the wild by some clients, notably Jitsi Meet)
Some other implementations I know of that use XEP-0172:
- Cheogram <https://wiki.soprani.ca/CheogramApp/Nickname>
- Slidge (compatible with Cheogram to encode nicknames that are not
valid resource parts — at least according to the libs I have used, cf above)
- Maybe gajim some day if I ever find the energy to rebase and finish
<https://dev.gajim.org/gajim/gajim/-/merge_requests/999>
Now, the question that has been burning my lips: is "New MUC" the new
codename of "GC3" or are those supposed to be different things?
