title: UnicodeDecodeError: 'utf8' codec can't decode byte 0xa3 in position 3: invalid start byte
body: <p>I am using <code>repl.it</code> Python web IDE, and I really can't solve a problem with it.</p>
  
  <p>I was trying to decode a string, but it seems that there's no way to do it.</p>
  
  <pre><code>import base64
  
  ciphertext = 'FxM7o1wl/7wE9CHPNzbB944feDFXbTSVaJfaLsUMzH5EP4xZRz7Sq8O3y7+jPbXIMVRxpvJZZm7ugqQ4fwpJwtvnB0/BoU+hhGeEZZZ0fFj1irm/zg3bsxOoxBJx4B3U'
  
  ciphertext = base64.b64decode(ciphertext)
  
  print ciphertext
