Steps to replicate the issue:
- Start editing a wiki page (Visual Editor or wikitext editor).
- Open the special characters menu.
- Search for ß (lowercase) and ẞ (uppercase) (compare Wikipedia article).
What happens?:
The lowercase character is in the Latin group, while the uppercase character is in the Latin extended group.
What should have happened instead?:
Both characters should be next to each other in the Latin group (ideally, placed after Ș ș).
