title: How do I represent an empty Char in Scala?
body: <pre><code>val mychar=''
  </code></pre>
  
  <p>Does not compile and results in the following error:</p>
  
  <blockquote>
    <p>error: unclosed character literal</p>
  </blockquote>
  
  <pre><code>val mychar='a'
  </code></pre>
  
  <p>etc is fine. I've tried playing around with converting "" to char but without much luck</p>
