In Django 1.5 the slug validator uses this regex:

slug_re = re.compile(r'^[-a-zA-Z0-9_]+$')

See https://github.com/django/django/blob/stable/1.5.x/django/core/validators.py#L106

You can use this regex in urls.py:

url(r'^post/(?P[-a-zA-Z0-9_]+)/$', ...

In earlier versions it was [-\w]+ but I guess in Python3 \w matches non ascii characters like umlauts.
