title: C# String ASCII representation
body: <p>How can I insert ASCII special characters (e.g. with the ASCII value 0x01) into a string?</p>
  
  <p>I ask because I am using the following:</p>
  
  <pre><code>str.Replace( "&lt;TAG1&gt;", Convert.ToChar(0x01).ToString() );
  </code></pre>
  
  <p>and I feel that there must be a better way than this. Any Ideas?</p>
  
  <p>Update:</p>
  
  <p>Also If I use this methodology, do I need to worry about unicode &amp; ASCII clashing?</p>
