If you want to include non-ASCII characters in your email headers, say in the
:mailheader:`Subject` or :mailheader:`To` fields, you should use the
-:class:`Header` class and assign the field in the :class:`Message` object to an
-instance of :class:`Header` instead of using a string for the header value.
-Import the :class:`Header` class from the :mod:`email.header` module. For

Notice here how we wanted the :mailheader:`Subject` field to contain a non-ASCII
character? We did this by creating a :class:`Header` instance and passing in
the character set that the byte string was encoded in. When the subsequent
-:class:`Message` instance was flattened, the :mailheader:`Subject` field was
-properly :rfc:`2047` encoded. MIME-aware mail readers would show this header
-using the embedded ISO-8859-1 character.
