The usual method in the Python compare logic is to revert to
the type name for compares in case coercion fails... I think
this is the right description in this case: decoding fails and
thus coercion becomes impossible.
PyObject_Compare() has the logic, we'd just have to reenable
it for Unicode which currently is handled as special case to
pass through the decoding error.
Note that Unicode objects which don't coerce would then always
compare larger than 8-bit strings ("unicode" > "string").
