title: Django replaces non-ascii characters with \ufffd
body: <p>Within my project, when I am submitting some data with non-ascii characters to the form, I am getting all non-ascii data replaced with unicode replacement character \ufffd. In the view that receives the data from the form, I have this malformed strings in request.POST. Seems I've missed something obvious.</p>
  
  <p>My environment:</p>
  
  <ul>
  <li>Python 2.6</li>
  <li>Django 1.3 alpha 1</li>
  <li>MySQL 5.1, database uses UTF-8 charset</li>
  </ul>
  
  <p>Have reproduced this issue using development server locally and intermediate server running Apache+mod_wsgi, with Firefox 4 and Chrome 11.</p>
  
  <p>Where should I look to workout the problem? Thanks.</p>
  
  <p><strong>Update:</strong> below is the code I am using -</p>
  
  <pre><code>@render_to('mail/new_message.html')
  @login_required
  def new_message(request, user_id):
      user = request.user
  
      if request.method == 'POST':
          form = MessageForm(request.POST, request.FILES)
          # exclude attachment from init instance, because we need instance id
          # for saving attachment
          form._meta.exclude = ['attachment']
          if form.is_valid():
              new_msg = form.save()
              new_msg.sender = user
              if form.cleaned_data['attachment']:
                  new_msg.attachment = form.cleaned_data['attachment']
              new_msg.save()
              message_sent.send(sender=None,instance=new_msg)
              return HttpResponseRedirect(reverse(messages))
      else:
          initial = {}
          if user_id:
              initial['receivers'] = [user_id,]
          form = MessageForm(initial=initial)
      return {'form': form}
  </code></pre>
