title: Unicode not recognised when running react native app on iPad
body: <p>I have a this element in a react-native app I've been using to learn, based on the tutorial.   It renders fine in the desktop, on the iPad Pro simulator:</p>
  
  <pre><code>var MainPageTopBar = React.createClass({
      render: function() {
          return (
              &lt;View style={styles.topBar}&gt;
                  &lt;Text&gt;{'\u25BC'} Jobs&lt;/Text&gt;
                  &lt;Text&gt;{'\u2795'}|{'\u{1F50D}'}&lt;/Text&gt;
              &lt;/View&gt;
          );
      }
  });
  </code></pre>
  
  <p>However, when I follow <a href="https://facebook.github.io/react-native/docs/running-on-device-ios.html#content" rel="nofollow">the instructions for running on device</a> (using the development server), I get:</p>
  
  <pre><code>SyntaxError: \u can only be followed by a Unicode character sequence
  
  {   
      "line": 1146,   
      "sourceURL": "http://192.168.178.22:8081/index.ios.bundle?platform=ios&amp;dev=true"
   } 
  </code></pre>
  
  <p>If I delete the unicode characters out of the above code, it works fine on the device.</p>
  
  <p>What is going on here?  </p>
  
  <hr>
  
  <p>(I'd also like to know what line of what file that error message is referring to: IE how would I go about debugging this if I didn't already know where the unicode characters were?  Because there is no file I can find of that name, or with unicode at line 1446.)</p>
