Hello,
On most wikis, MediaWiki is configuration to convert the first letter of a title to uppercase, but apparently it's not converting every Unicode characters : for example, on frwiki ɽ https://fr.wikipedia.org/w/index.php?title=%C9%BD&redirect=no is a different article than Ɽ https://fr.wikipedia.org/wiki/%E2%B1%A4, even if the second character is the uppercase version of the first one in Unicode.
So, what characters are actually converted to uppercase by the title normalization ?
I need to know this information to stop reporting some false positives in WPCleaner https://fr.wikipedia.org/wiki/Wikip%C3%A9dia:WPCleaner.
Thanks, Nico
