Problems with the locale updates are not limited to non-ASCII characters, sorting rules involving "-" changed, for instance. When you make that OS upgrade, you really, really, need to reindex all text types.
That's precisely why I'm using logical replication for this migration. The indexes are new on the subscriber server. Re-indexing should only be necessary if I were to do physical replication/restore onto a 22.04 server, no?
