Description

I have a table with a CharField primary key:

class PagesInternal(models.Model):
    name = models.CharField(primary_key=True, maxlength=150)
    ...

I get a error, if i edit a entry (with pk='page_admin.edit_page') with the django admin panel:

Traceback (most recent call last):

  UnicodeDecodeError at /_admin/PyLucid/pagesinternal/page_admin.edit_page/
  'utf8' codec can't decode byte 0xad in position 4: unexpected code byte

The problem is not directly this UnicodeDecodeError! It's a problem with the quote()/unquote() routines in django.contrib.admin.views.main.py and the character combination "_ad" (a valid hex digits).

The real problem is: The primary key string runs through unquote(), but it doesn't run through quote() previously! Probably the error is in change_stage(). I don't known why quote() is not used.

btw. I use a work-a-round and replace all underscores to spaces :-/

This should be fixed before the merge of newforms-admin into trunk. Marking as a blocker.
