Hi.

>From RFC 2047:
+ An 'encoded-word' MUST NOT appear in any portion of an 'addr-spec'.
+ An 'encoded-word' MUST NOT appear within a 'quoted-string'.
+ An 'encoded-word' MUST NOT be used in a Received header field.
+ An 'encoded-word' MUST NOT be used in parameter of a MIME
  Content-Type or Content-Disposition field, or in any structured
  field body except within a 'comment' or 'phrase'.


However (Python 2.5.2):

>>> h = Header(u'Andrè <andre at localhost>')
>>> h.encode()
'=?utf-8?b?QW5kcsOoIDxhbmRyZUBsb2NhbGhvc3Q+?='


I'm not sure if this can be considered a bug, but surely this is an 
invalid header.



Thanks  Manlio Perillo
