The following two pages only different on an inivisible unicode character https://bo.wikipedia.org/wiki/%E0%BD%94%E0%BD%BC%E0%BD%A3%E0%BC%8B%E0%BD%9D%E0%BC%8B%E0%BD%A3%E0%BD%BA%E0%BC%8B%E0%BD%A2%E0%BD%B2%E0%BC%8D https://bo.wikipedia.org/wiki/%E0%BD%94%E0%BD%BC%E0%BD%A3%E2%80%8B%E0%BC%8B%E0%BD%9D%E0%BC%8B%E0%BD%A3%E0%BD%BA%E0%BC%8B%E0%BD%A2%E0%BD%B2%E0%BC%8D the should point at the same page but they don't. This causes a lot of interwiki bots to add invisible unicode characters (https://en.wikipedia.org/w/index.php?title=Paul_Val%C3%A9ry&diff=521762765&oldid=521723299) The three characters that cause similar problems are \u200E|\uFEFF|\u200B
I suspect that due to these characters the page can't be called directly by typing its title.
I also left a message here: https://meta.wikimedia.org/wiki/Talk:Steward_requests/Bot_status#Remove_invisible_unicode_characters_from_pagetitles_in_various_projects
An example of how I resolved it manually by removing the invisible character https://my.wikipedia.org/w/index.php?title=%E1%80%9C%E1%80%B0%E1%80%9D%E1%80%AE%E1%80%B8%E1%80%82%E1%80%BB%E1%80%AE_%E1%80%82%E1%80%AB%E1%80%9C%E1%80%BA%E1%80%97%E1%80%AC%E1%80%B8%E1%80%94%E1%80%AE&diff=prev&oldid=187495
Added some previous similar bugs.
The bug may cause serious problems to interwiki bots https://km.wikipedia.org/w/index.php?title=%E1%9E%91%E1%9F%92%E1%9E%9A%E1%9E%B9%E1%9E%9F%E1%9F%92%E1%9E%8F%E1%9E%B8%E1%9E%94%E1%9E%91%E1%9E%80%E1%9E%BC%E1%9E%9F%E1%9F%8A%E1%9E%B8%E1%9E%93%E1%9E%BB%E1%9E%9F&action=history Some bypass the redirect, some note, splitting the interwiki links around
