According to
http://docs.python.org/library/email.message.html?highlight=3Dadd_header#em=
ail.message.Message.add_header

For each item in the keyword argument dictionary _params, the key is taken =
as
the parameter name, with underscores converted to dashes (since dashes are
illegal in Python identifiers). Normally, the parameter will be added as
key=3D"value" unless the value is None, in which case only the key will be =
added.
If the value contains non-ASCII characters, it must be specified as a three
tuple in the format (CHARSET, LANGUAGE, VALUE), where CHARSET is a string
naming the charset to be used to encode the value, LANGUAGE can usually be =
set
to None or the empty string (see RFC 2231 for other possibilities), and VAL=
UE
is the string value containing non-ASCII code points.

An example with non-ASCII characters:

msg.add_header('Content-Disposition', 'attachment',
               filename=3D('iso-8859-1', '', 'Fu=C3=9Fballer.ppt'))

Which produces

Content-Disposition: attachment; filename*=3D"iso-8859-1''Fu%DFballer.ppt"
