title: How can I use special characters in angular directives attributes?
body: <p>I would like to use strings including german characters (Ä, Ö, Ü) in attributes of a custom angularJS directive.</p>
  
  <p>For example:</p>
  
  <pre><code>&lt;my-custom-directive my-label="Lärm" /&gt;
  </code></pre>
  
  <p>Another example is the <a href="http://angular-ui.github.io/bootstrap/#/tabs" rel="nofollow">ui.bootstrap.tabs</a> directive:</p>
  
  <pre><code>&lt;tabset&gt;
     &lt;tab heading="Lärm"&gt; content ... &lt;/tab&gt;
     &lt;tab heading="Second Heading"&gt; content ... &lt;/tab&gt;
  &lt;/tabset&gt;
  </code></pre>
  
  <p>This results in a tab with heading "L�rm". Any ideas?</p>
