title: Using non-ASCII character as JavaScript object key
body: <p>I have the following object:</p>
  <pre><code>var obj = {
    'ア' : 'testing',
    'ダ' : '2015-5-15',
    'ル' : 123,
    'ト' : 'Good'
  };
  </code></pre>
  <p>How do I access the values by its non-ASCII key (it's a Japanese character in this case)?</p>
  <p>Can't use <code>obj.ア</code> or <code>obj.'ア'</code> for sure, which will give JavaScript parse error.</p>
