title: How to detect emoji using javascript
body: <p>I need help for how to detect if an input contains a Japanese emoji/emoticon.</p>
  
  <p>Currently my character set is <code>charset=utf-8</code>. On inputting text, the user can enter Japanese characters/alpanumerics/symbols but if they insert an emoji, <code>onsubmit</code> JavaScript will check if there is an emoji, error message will display.</p>
  
  <p>I can't get this to work because I have no idea on how to detect an emoji in JavaScript?</p>
