title: Which encoding uses the \x (backslash x) prefix?
body: <p>I'm attempting to decode text which is prefixing certain 'special characters' with <strong>\x</strong>. I've worked out the following mappings by hand:</p>
  
  <pre><code>\x28   (
  \x29   )
  \x3a   :
  
  e.g. 12\x3a39\x3a03 AM
  </code></pre>
  
  <p>Does anyone recognise what this encoding is?</p>
