Here is the output when run through mimedecode

See how the part's Content-Transfer-Encoding still is 7bit even
though the part contains an 8bit character (e acute (0xE9)).
I would have expected something like:
| MIME-Version: 1.0
| Content-Type: multipart/mixed;
| boundary="----_=_NextPart_026_01C81003.683F8A00"
|
| ------_=_NextPart_026_01C81003.683F8A00
| Content-Type: message/rfc822
| X-Content-transfer-encoding: changed from 7bit
| Content-Transfer-Encoding: 8bit
|
| Content-Type: text/plain;
| charset="iso-8859-1"
| X-Content-transfer-encoding: fixed from quoted-printable
| Content-Transfer-Encoding: 8bit
