About "brave" in BIP39

"brave" has 5 letters, but the first four, "brav", already identify it, because "bra" also begins bracket, brain, brand and brass.
The same spelling is in the French BIP39 wordlist, but as word #278 (index 277), not #219. A wallet set to French reads "brave" as 00100010101 instead of 00011011010, and decodes index 218 as "bélier".
"brav" is unique only within the English list: it also begins bravo in the Spanish list, bravura in the Italian list and braveza in the Portuguese list, so a four-letter backup should say which list it uses.
"brave" appears in one of the 24 official English test vectors of BIP39: vector #17 (word 18 of 18). Every official vector passes the checksum checker, and How BIP39 works shows how the entropy turns into such words. As the last word of vector #17, its final 6 bits, 011010, are the checksum of the 18-word phrase.
