title: Make iOs VoiceOver spell out abbreviated "W" as "Watt"
body: <p>I'm adding accessibility support to an app where one part of the app is a UIWebView with text information. 
  The text contains abbreviated units such as W for watt, lm for lumen, etc...</p>
  
  <p>The VoiceOver functionality does not by it self recognize the letter W as watt (of course it is hard) and it needs some help.</p>
  
  <p>I know about the html tags  and  (http://www.w3schools.com/tags/tag_abbr.asp)</p>
  
  <p>Eg. </p>
  
  <pre><code>15 &lt;ABBR title='Watt'&gt;W&lt;/ABBR&gt;&lt;br&gt;
  15 &lt;ACRONYM title='Watt'&gt;W&lt;/ACRONYM&gt;&lt;br&gt;
  </code></pre>
  
  <p>Unfortunately they are not recognized by the VoiceOver system.</p>
  
  <p>Does anybody know a way to make this work?</p>
