title: Check whether a string contains Japanese/Chinese characters
body: <p>I need a way to check whether a string contains <strong>Japanese</strong> <strong>or</strong> <strong>Chinese</strong> text.</p>
  
  <p>Currently I'm using this:</p>
  
  <pre><code>string.match(/[\u3400-\u9FBF]/);
  </code></pre>
  
  <p>but it does not work with this for example: <code>ディアボリックラヴァーズ</code> or <code>バッテリー</code>.</p>
  
  <p>Could you help me with that?</p>
  
  <p>Thanks</p>
