SMTP message header has to be encoded specially if it contains non ascii 
characters. Subject has to be of the form:
=?<enc>?b?<text>?=

and text should be base64 encoded.

Here is a simple script that will generate proper header value for a UTF-8 
string:

import base64
def encode_smtp_header (s):
   m = base64.encodestring (s.strip ()).strip ()
   return "=?%s?%s?%s?=" % ('utf-8','b', m)
