Just as reminder: we have the general purpose
encode()/decode() functions in the codecs module:

import codecs
r13 = codecs.encode('hello world', 'rot-13')

These interface directly to the codec interfaces, without
enforcing type restrictions. The codec defines the supported
input and output types.
