Again, no characters are treated as special here.
Everything that applies to '@' applies to anything else, as well. IF you decide to
send extra characters with your mentions, you include them in the range. It doesn't
matter what those characters are. The receiver shouldn't need to care either;
that's kind of the entire point.
I guess that's where we disagree. As a receiving implementation, why
would you have to display an "implementation detail" from another
client? You can't actually remove that implementation detail if you feel
it should not be displayed in your client, as you do not understand it.
