title: StandardCharsets.UTF_8 on lower API lower than 19
body: <p>I'm using this code to get scandinavian characters posted to php correctly.</p>
  
  <p>Issue here is that StandardCharsets.UTF_8 is not supported before API 19</p>
  
  <pre><code>byte[] postData = urlParameters.getBytes(StandardCharsets.UTF_8);
  
  DataOutputStream wr = new DataOutputStream( con.getOutputStream());
  wr.write( postData );
  </code></pre>
  
  <p>Field requires API level 19 (Current min is 14): java.nio.charset.StandardCharsets#UTF_8</p>
  
  <p>How should I do this with API lower than 19?</p>
