title: Which characters are permitted in django (1.4) passwords?
body: <p>I just started working with Django 1.4 recently. I remember when I worked with 1.3 that there was a list of characters which were allowed as password characters. It included the usual alphanumeric as well as a few special characters, such as $, %, _, and @.</p>
  
  <p>Does anyone know where in the documentation I can find the list of permitted password characters?</p>
  
  <p>Thanks.</p>
