Ah, I see.
Yes, that won't work.
Hyperlinking of usernames and automatic "mentions" are driven by Twitter's convention on what is a username.
https://support.twitter.com/articles/101299#
Twitter only allows the following in usernames:
- alphanumeric characters (letters A-Z, numbers 0-9)
- underscores
- 15 characters or shorter
We already break the rules a little, we allow up to 40 characters. And we also allow unicode to work too.
But... if a username contains anything that is going to be escaped as a HTML entity, i.e. & > or < ... then the username matcher is only going to find the bits up to the ampersand... meaning it actually finds @b and as there is no user called "b", it thinks there is no match.
I'm happy to let anyone choose whatever username they want, but some will limit functionality.
- alphanumeric characters (letters A-Z, numbers 0-9)

Oh, this doesn't work either.
@Velocio to the rescue?
