Handles extra types compared to the built-in :class:`json.JSONEncoder`. - :class:`datetime.datetime` and :class:`datetime.date` are serialized to :rfc:`822` strings. This is the same as the HTTP date format. - :class:`uuid.UUID` is serialized to a string. - :class:`dataclasses.dataclass` is passed to :func:`dataclasses.asdict`. - :class:`~markupsafe.Markup` (or any object with a ``__html__`` method) will call the ``__html__`` method to get a string.
