class Actor(models.Model):
    name = models.CharField(max_length=20, primary_key=True)

when trying to save it:

>>> travolta.save()
There is UnicodeDecodeError at:
django.db.base.Model -> save function:

        pk_set = pk_val is not None and pk_val != u''
    UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 2: ordinal not in range(128)

fix should use smart_unicode like:
pk_set = pk_val is not None and smart_unicode(pk_val) != u''"		closed	Core (Other)	dev		fixed	unicode primary key pk		Ready for checkin	1	0	0	0	0	0
