title: Regex for Apostrophe
body: <p>I am looking for a regular expression that will look for Apostrophe in a string. The string can be a sentence too. I tried a simple regex like (') but it only checks for one character in a string. How to I check for the entire string. </p>
  
  <p>For example. </p>
  
  <pre><code>"Hello! I have many PC's"
  </code></pre>
  
  <p>will be a match" 
  but </p>
  
  <pre><code> "@#%@^@&amp;%@!%!::"";[] I dont have any PCs)" 
  </code></pre>
  
  <p>will be a mismatch (basically any character except Apostrophe)"</p>
  
  <p>Thanks</p>
