title: Finding null character using Regex in Perl
body: <p>I want to find the null characters in an array, which I have. I tried displaying the ASCII value and it printed 0 (So I am confirmed it is a null value). How do I write a regex to filter out those values.</p>
  
  <p>I wrote :</p>
  
  <pre><code>m/^$/ig 
  </code></pre>
  
  <p>which really didn't help me. Does anybody know how to match a null character ?</p>
