If use a non-builtin codec, partially implemented in Python (e.g. ISO-8859-15), a new RecursionError (with empty error message) can be raised while handle a RecursionError. Testing for error message was needed to distinguish a recursion error from arbitrary RuntimeError. After introducing RecursionError, it became unnecessary.
