Nick with { or } show up "=7B" and "=7D"

[kroeckx]

Someone with the nick {hoshi} on IRC shows up as _ircnet_=7bhoshi=7d in the room. Everything related to that nick is shown as that.

This is correct for the user_id, but not for the display name. Can you screenshot it / show me the users member state?

Is that what you're looking for?

Duplicate of #498?

@Mikaela I'm getitng this issue on Freenode (see element-hq/element-web#9771), so it's probably a different issue (given that #498 explicitly mentions that Freenode is not affected).

[Half-Shot]

This is a bit different. I believe it's because we now escape nicks for the purpose of shoving them in mxids (Matrix forbids a lot of characters, and we've been abusing this for years). My theory is that the displayname of IRC users is being wrongfully set to the localpart of their mxid.

This is fixed by #750

This also seems to affect nicks containing pipe (|) characters. On the current Riot web version, this is still an issue.

@mfiano Have you seen #767 ? I wonder if you referred to it or it has gotten more broken since May the 23th.

My theory is that the displayname of IRC users is being wrongfully set to the localpart of their mxid.

I've been seeing @freenode_=7b^_^=7d:matrix.org show up as =7b^_^=7d for months; note that this is not the localpart of the mxid.

FYI #768 hopes to disable the feature entirely until I have more time to make the whole IRC bridge cooperate with escaping.

Closing this PR, please use #744 for reporting issues of this type as they seem to all be related.
