title: C# Regex Escape Sequences
body: <p>Is there a <em>complete</em> list of regex escape sequences somewhere? I found <a href="http://www.mikesdotnetting.com/Article/46/CSharp-Regular-Expressions-Cheat-Sheet" rel="noreferrer">this</a>, but it was missing <code>\\</code> and <code>\e</code> for starters. Thus far I have come up with this regex pattern that hopefully matches all the escape sequences:</p>
  
  <pre><code> @"\\([bBdDfnreasStvwWnAZG\\]|x[A-Z0-9]{2}|u[A-Z0-9]{4}|\d{1,3}|k&lt;\w+&gt;)"
  </code></pre>
