It doesn’t matter too much. It’s well past the point where fully random passwords are impossible to brute force in this universe. Even well conceived passphrases won’t get that long. If you’re really bothered by it, you can sha256 the input before feeding it to bcrypt/scrypt, but it doesn’t really matter.
Damm, I legit didn’t knew there bcrypt had a length limit! Thank you for another reason not to use bcrypt
Scrypt has the same limit, FWIW.
