About "ozone" in BIP39

Two letters are enough: no other BIP39 word begins with "oz", which makes "ozone" one of only 34 words that can be told apart this early.
The same spelling is in the French BIP39 wordlist, but as word #1410 (index 1409), not #1269. A wallet set to French reads "ozone" as 10110000001 instead of 10011110100, and decodes index 1268 as "monument".
"ozon" is unique only within the English list: it also begins ozono in the Spanish list, so a four-letter backup should say which list it uses.
"ozone" appears in one of the 24 official English test vectors of BIP39: vector #13 (word 1 of 12). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words.
