Sorry for responding so late.

Getting ? characters when you print to the console does not
*necessarily* mean python is doing anything wrong.  It may be outputting
the correct characters, but your console lacks the proper font for
displaying those characters.  Try doing for c in email_body: print
hex(ord(c)), and see if the results correspond to what you're trying to
get.
