Answer 1

Vous devez simplement ajouter 'utf-8' argument à votre MIMEText des appels (il suppose 'us-ascii' par défaut).

Par exemple:

 # -*- encoding: utf-8 -*-

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

msg = MIMEMultipart("alternative")
msg["Subject"] = u'テストメール'
part1 = MIMEText(u'\u3053\u3093\u306b\u3061\u306f\u3001\u4e16\u754c\uff01\n',
                 "plain", "utf-8")
msg.attach(part1)

print msg.as_string().encode('ascii')
