title: How to put a “-” in string.xml file, but without escaping
body: <p>I have a configuration.xml file which I hold all the (yep, you guessed it!).. configuration strings and values and stuff.</p>
  
  <p>One of those values is a string which is an oauth client id, and it has a hyphen..</p>
  
  <pre><code>&lt;string name="server_clientid"&gt;5467656-blahblahblah.apps.googleusercontent.com&lt;/string&gt;
  </code></pre>
  
  <p>Now I get the warning message..</p>
  
  <pre><code>Replace "-" with an "en dash" character (–, &amp;#8211;) ?
  </code></pre>
  
  <p>Ok fair enough, but if I escape with this then the client id is not valid when I fetch it within the app. I can't use &amp; #8211; basically. How do I get around this?</p>
