**Background**
To enable the migration from PHP 7.4 (Unicode 11) to 8.1 (Unicode 14), we overrode MediaWiki's title-casing behavior to always behave like PHP 7.4, despite the distinct Unicode versions they support (see T372603 for details).
Now that the migration is complete, we need to remove the overrides, thus adopting PHP 8.1 title-casing behavior. However, before doing so, we need to perform a number of page and image renames to be consistent with the latter.
The purpose of this task is to track this renaming process (see the parent task for technical details), which we expect to complete the week of 30 June.
**Planned renames**
NOTE: Editors are requested to NOT edit these pages or the old titles during the transition. The SRE team will both move the pages to their new titles, and also fix incoming links/calls to those pages a few minutes afterwards via a backend configuration change.
As of 2025-06-30, this will involve 76 page renames (52 with deletion of then-obsolete duplicate redirects), 3 image renames, and 1 user renames, across 15 wikis:
