Incomplete string escaping or encoding High
There was a problem hiding this comment.
MENTION_RE doesn't match backslashes, so re cannot contain escaped underscores.
The reason escaping here works is because redcarpet converts escaped underscores to underscores instead of u elements before mentions are processed in rewrite
I haven't looked into why manually escaping usernames doesn't produce a mention, but I think that's expected behaviour.

Fixes #2432
Not the best solution, but the easiest I could think of not requiring a major refactor.
This will force escape underscores in mentions.
This will still not link correctly when content type is html, but I consider that a separate issue.
