Incorrect escaping of IRC(?) nicknames

[joepie91]

Description

Nicknames from IRC(?) get incorrectly escaped for certain special characters.

Steps to reproduce

• Enter #freenode_#bottest:matrix.org
• Post a GitHub link, like https://github.com/vector-im/riot-web/issues/7134, wait for the bot to respond with the issue title
• Notice the wrong bot nickname :)

Original on IRC:

[10:56] <joepie91[m]> sphalerite: https://github.com/vector-im/riot-web/issues/7134 :)
[10:56] <{^_^}> vector-im/riot-web#7134 (by turt2live, 41 weeks ago, open): Pills for users with backticks get converted to code when complimented with another backtick

Bot nickname display in Riot (desktop):

As you can see, some sort of encoding happens in the process, and turns the { into =7b, and the } into =7d. This should be displayed as {^_^} instead of =7b^_^=7d.

I don't know whether this is a bug in the IRC bridge or in Riot.

This looks to be a duplicate of #9662, where it was mentioned that the actual issue is tracked at matrix-org/matrix-appservice-irc#749, so it's a bridge issue.

Ah, I didn't find that issue in my search. Thanks :)
