title: JSON Parse Error for Undefined and weird Character
body: <p>I'm facing a weird problem, I am using Ruby JSON to parse a string but failed to do so. I am getting a weird character in near the beginning of the string which only shows up in C9 Editor or JSLINT website. I can neither copy or paste this character.</p>
  
  <p>I am attaching a screenshot of the same.<a href="https://i.stack.imgur.com/pBbgU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pBbgU.png" alt="JSLINT SCREENSHOT"></a></p>
  
  <p>How Can I Parse this string as I get <code>unexpected token</code> error. Also can someone tell what this character is?</p>
  
  <p>update: Trying to paste the string here.
  <code>
  bar = "{\"id\":3710}"
  </code></p>
