Content
PyUnicode_AsEncodedObject() can return an object of arbitrary type, while PyUnicode_AsEncodedString() always returns bytes. The code that uses PyUnicode_AsEncodedObject() in the _curses module expects bytes, but does not check the type of the result. This can cause undefined behavior, including a crash. Using PyUnicode_AsEncodedString() is more correct in this case.
