title: Dump in PyYaml as utf-8
body: <p>I'm trying to load a bunch of utf-8 encoded strings and dump them again with PyYaml. This is the code for loading/dumping:</p>
  
  <pre><code>lang_yml = yaml.load(codecs.open(lang + ".yml.old", "r", "utf-8"))
  test_file_path = lang + '.yml'
  stream = file(test_file_path, 'w')
  yaml.dump(lang_yml, stream,  default_flow_style=False, encoding=('utf-8'))
  </code></pre>
  
  <p>But a strings that start as "En arrière" ends up being saved as "En arri\xE8re".
  What am I doing wrong?</p>
