As for ciphers, I'd say that 27 is Y would make sense in a substitution cipher, but only for an alphabet with 27 or more characters.

Ah, now I know what sense of cipher you meant.

JEDIT: Probably worth saying that only parts of the "French" above were written with Google. Other parts were just..attempted.

Indeed.
