Choices Field is not shown in UserAdmin when an special sign is in the choices

[marco.roose@…]

I have the following model:

# -*- coding: iso-8859-1 -*-

from django.contrib.auth.models import AbstractUser
from django.db import models


class Nutzer(AbstractUser):
    NOTREGISTERED = "NR"
    NOTPROOFED = 'NP'
    NOTPAYED = 'NPY'
    EXPERIED = "EXP"
    OK = 'OK'

    MARKETSTATUSCHOICES = (
        (NOTREGISTERED, 'Du bist nicht registriert'),
        (NOTPROOFED, 'Deine Anfrage wird geprüft'),
        (NOTPAYED, 'Wir warten auf Deine Beitragszahlung'),
        (OK, 'Du kannst tauschen'),
        (EXPERIED, 'Dein Konto wurde gesperrt')
    )
    market_status = models.CharField(choices=MARKETSTATUSCHOICES, verbose_name="Tausch-Status", max_length=30, default=NOTREGISTERED)

and a "normal" Useradmin like the one from the docs. In the Nutzer change form the "market_status" field is not rendered (but the label).

If I change the NOTPROOFED to have a description without the German Umlaut the field is rendered as expected.

I fiddled around a bit:

(NOTPROOFED, u'Deine Anfrage wird geprüft'),

does work. So it seems to be some unicode problem?

Yes, it's an error in your app, not Django. Consider using ​unicode_literals.
