body: <p>Consider this <a href="https://codegolf.stackexchange.com/questions/18721/hello-world-without-repetition/18808#18808">answer</a>.</p>
  
  <p>I saw the question and tried to convert JavaScript to C# code:</p>
  
  <p>This is the JavaScript code:</p>
  
  <pre><code>alert('Hel\x6co wor\x6cd!')//alert hello world 
  </code></pre>
  
  <p>What I got when I converted to C#</p>
  
  <pre><code>Console.WriteLine("Hello w\x6fr\x006cd!");//write hello world!
  </code></pre>
  
  <p>How does compiler know convert the code to <code>hello world!</code>?</p>
