python - Django 1.5 UnicodeEncodeError using attach_alternative in emails -

i'm in process of migrating django project 1.3 1.5.

one app sends emails not working in 1.5 in development machine. error:

unicodeencodeerror @ /envia_activacion/ 'ascii' codec can't encode character u'\xf3' in position 37: ordinal not in range(128)

my code this:

plaintext = get_template('emailing/activacion.txt') htmly = get_template('emailing/activacion.html') //html template utf-8 charset d = context({     'code': code,     'version': sversion,     'activacion': activacion,     'distribuidor': distribuidor,     'contacto': contacto,     'departamento': departamento,     'empresa': empresa              })  asunto = u'código activación %s - v%s - code: %s' % (nombre_destinatario, version, code) text_content = plaintext.render(d) html_content = htmly.render(d)  msg = emailmultialternatives(asunto, text_content, remitente, para, [remitente], headers={'reply-to': remitente}) msg.attach_alternative(html_content, "text/html")//this makes fail  msg.send() 

this works in django 1.3, don't know in django 1.4.

debugging, see text fails unicode:

> /usr/lib/python2.6/email/generator.py(178)_handle_text() -> self._fp.write(payload) (pdb) s unicodeencodeerror: unicodee...ge(128)') > /usr/lib/python2.6/email/generator.py(178)_handle_text() -> self._fp.write(payload) (pdb) payload u'apreciado cliente, le indicamos los c\xf3digos necesarios ...' 

i'm using python 2.6.5. i've reviewed ticket looks same https://code.djangoproject.com/ticket/19107 in django 1.5 patch exists , i'm still getting error.

i appreciate help. thanks

your payload unicode instance (note django strives use unicode internally) while should str instance. it's responsability pass (preferably encoded) str. quite easy fwiw:

# assume use utf-8 everywhere  text_content = plaintext.render(d).encode("utf-8") html_content = htmly.render(d).encode("utf-8")
