title: UnicodeDecodeError with Django's request.FILES
body: <p>I have the following code in the view call..</p>
  
  <pre><code>def view(request):
      body = u""  
      for filename, f in request.FILES.items():
          body = body + 'Filename: ' + filename + '\n' + f.read() + '\n'
  </code></pre>
  
  <p>On some cases I get</p>
  
  <pre><code>UnicodeDecodeError: 'ascii' codec can't decode byte 0xf0 in position 7470: ordinal not in range(128)
  </code></pre>
  
  <p>What am I doing wrong? (I am using Django 1.1.)</p>
  
  <p>Thank you.</p>
