title: RegEX to match unicode Java Escaped characters
body: <p>I am trying to write a regular expression which finds all unicodes and removes it.</p>
  
  <p>Example:</p>
  
  <blockquote>
    <p>\ud83e \udd80</p>
  </blockquote>
  
  <p>When I do this:<code>[^\u0000-\u007F]</code>, it matches the actual single unicode character.</p>
  
  <p>What I am trying to match is the actual backslash with the five characters in front</p>
  
  <p>how can I do that?</p>
