Dupe of T297342: Expose phpCharToUpper map for title normalization via the API?

I would say related, because I am asking for https://github.com/wikimedia/operations-mediawiki-config gets to be updated (it is just a static setting, no?), and not for an API. API would be cool, too.

Oh, the custom $wgOverrideUcfirstCharacters were removed in https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/726623 - they're no longer used on Wikimedia sites. If it's not in that Git repo, it's not deployed basically.

Oh, thanks. That is good to now. This resolves things for me.

Thanks for fixing the status.

Are you sure there are no overrides? Because I do not get why the following file does not get the first character upper case: https://commons.wikimedia.org/w/api.php?action=query&titles=File:%E1%83%90%E1%83%9A%E1%83%94%E1%83%95%E1%83%98%E1%83%A1%20%E1%83%A1%E1%83%90%E1%83%9B%E1%83%94%E1%83%91%E1%83%98%E1%83%A1%20%E1%83%9B%E1%83%9D%E1%83%9C%E1%83%90%E1%83%A1%E1%83%A2%E1%83%94%E1%83%A0%E1%83%98.jpg&format=json

But PHP ucfirst in includes/language/Language.php does make it upper case: http://sandbox.onlinephpfunctions.com/code/95b81ba34df4ece882a9ae74a64281da95f4b295

We're still running PHP 7.2, some of the ucfirst bugs were fixed in 7.3. See https://3v4l.org/lo6ro which shows the difference across PHP versions.

Oh, what will then happen when you upgrade PHP? Is there a ticket to track about it and issues related to title names because of it? So then upgrade will change title of the page I linked above.
