document that lists of integers can be specified if encoding(octet) is used

This seems to be a good compromise: The API now strongly encourages
lists of characters, which are ideally suited to represent text, and
also allows lists of bytes if the encoding(octet) option is used.

    Especially for cryptographic applications, it as an advantage that
