We'd only need an ABC if info was added for supported input types.
However, that's not necessary since "encodes_to" and "decodes_to"  are
enough to identify Unicode encodings: "encodes_to in (None, bytes) and
decodes_to in (None, str)", so we don't need to track input type
support at all if the main question we want to answer is "is this a
Unicode codec or not?".
