title: UnicodeEncodeError: 'ascii' codec can't encode character
body: <p>When uploading files with non-ASCII characters I get UnicodeEncodeError:</p>
  
  <pre><code>Exception Type: UnicodeEncodeError at /admin/studio/newsitem/add/
  Exception Value: 'ascii' codec can't encode character u'\xf8' in position 78: ordinal not in range(128)
  </code></pre>
  
  <p>See <a href="http://dpaste.com/hold/243643/" rel="noreferrer">full stack trace</a>.</p>
  
  <p>I run Django 1.2 with MySQL and nginx and FastCGI. </p>
  
  <p>This is a problem that is fixed according to the <a href="http://code.djangoproject.com/ticket/6009" rel="noreferrer">Django Trac database</a>, but I still have the problem. Any suggestions on how to fix are welcome.</p>
  
  <p>EDIT: This is my image field:</p>
  
  <pre><code>image = models.ImageField(_('image'), upload_to='uploads/images', max_length=100)
  </code></pre>
