--- Comment #9 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- Ok. There are two issues playing a role here.
1) the 'correct' page name ends in a 0x200B ZERO WIDTH SPACE. This makes no sense, other than to annoy people. 2) the XML parser strips spaces around titles, including the 0x200B ZERO WIDTH SPACE. 3) Mediawiki does *not* do this
So, first of all, I will rename the article, so it no longer has the 0x200B ZERO WIDTH SPACE in the title. I will see if I can pinpoint the XML bug, so someone else may fix it. However, due to the fact bots are killing eachother about it, I suspect this is a small change somewhere in the python APIs - or default setting that changed.
Lastly, maybe we should broaden the discussion into mediawiki-tech -- should page titles be allowed to have unicode whitespace characters embedded, especially if they are invisible?
