Thread:User talk:CodeCat/French sorting/reply

It can, as long as it follows the default sorting. Currently, all templates that generate sort keys for French use  in Module:utilities. In the end, they should all use that, but it's a gradual process. If you find any that don't use it, let me know.

If you want to check, you can add a sort key and see if the entry ends up in Category:Sort key tracking/redundant or Category:Sort key tracking/needed (both are hidden). If it doesn't, then the template doesn't use  yet (or perhaps it does, but isn't giving it the sort key for some reason). But if it does, then you can see whether the sort key is redundant depending on which of the two categories it ends up in.
