A mystery fairly commonly reported at the en WP:VPT is caused by users copying an article or category name and pasting it into a link but accidentally picking up a bidi directionality indicator in the copy. Since these characters are invisible, users are often confused why the resultant link shows as a red link rather than a blue link. I'm not sure it's completely safe to do this, but should we consider stripping bidi indicators that are inside wikilinks (perhaps only if adjacent to a pipe or the opening or closing brackets) when an edit is submitted?
Yeah, invisible characters are evil. Any in wikilinks or similar stuff should probably be auto-stripped, whether on save or render (render would probably be simpler).
