All API that refers to the internal representation should be
changed or removed; in theory, that could be all API that has
char* arguments.

For example, PyString_From{String[AndSize]|Format} would either:
- have to grow an encoding argument
- assume a default encoding (either ASCII or UTF-8)
- change its signature to operate on Py_UNICODE* (although
  we don't have literals for these) or
- be removed

Likewise, PyString_AsString either goes away or changes its
return type.

String APIs that operate on PyObject* likely can stay as-is.
