title: Emoji symbol  in string.xml crashes app
body: <p>I would like to integrate the emoji symbol  in my android app. Therefore I looked up the hex code for the utf-8 symbol and added the following to my string.xml file:</p>
  
  <pre><code>&lt;string name="thumbsup"&gt;Perfect &lt;node&gt;&amp;#x1f44d;&amp;#x1f44d;&lt;/node&gt;&lt;/string&gt;
  </code></pre>
  
  <p>This should result into <code>Perfect </code>. However, instead my app crashes when the call activity tries to display this:</p>
  
  <pre><code>JNI DETECTED ERROR IN APPLICATION: input is not valid Modified UTF-8: illegal start byte 0xf0
  </code></pre>
  
  <p>Not particularly perfect ;)</p>
