Although it's not explicit, the question seems to be about the output of
encoding (and for symmetry, the input of decoding). In both of those
cases, valid output will consist only of ascii characters.
The input to encoding would have to remain bytes (that's the main purpose
of base64... to turn bytes into an ascii string).
