title: converting byte object to utf-8
body: <pre><code>k = b'\xf2-\x92\xe7\x98\x90@\xddF\xbf\x13I4\x92\x0f\xc5'
  </code></pre>
  
  <p>I tried encoding in 'utf-8', but I am getting an error </p>
  
  <pre><code>utf-8' codec can't decode byte 0xf2 in position 0: invalid continuation byte
  </code></pre>
  
  <p>How can I properly convert this to a string  object?</p>
