title: How to bind to a dictionary entry with key ending in '{'?
body: <p>I want to bind to a value in a dictionary property of an object. The dictionary key of this value is a string ending in '{'. How do I express this in XAML?</p>
  
  <p>I presumably need to escape this character somehow.</p>
  
  <p>Example XAML that doesn't work:</p>
  
  <pre><code>&lt;TextBlock Text="{Binding Attribs[test{]}" /&gt;
  </code></pre>
  
  <p>Here <code>Attribs</code> is a property on the datacontext object of type <code>IDictionary&lt;string, object&gt;</code></p>
