title: Infinity symbol in TextBlock
body: <p>I need infinity symbol in <code>TextBlock</code></p>
  
  <p>If I write <code>"&amp;#8734;"</code> in <code>TextBlock.Text</code> all good, in <code>TextBlock</code> "&#8734;" symbol.</p>
  
  <pre><code>&lt;TextBlock Text="&amp;#8734;"/&gt; 
  </code></pre>
  
  <p>But if I use <code>Converter</code>.</p>
  
  <pre><code>&lt;TextBlock Text="{Binding MyValue, Converter={StaticResource MyConverter}}"/&gt; 
  </code></pre>
  
  <p>I have <code>"&amp;#8734;"</code> text in <code>TextBlock</code>.</p>
  
  <pre><code> public class MyConverter : IValueConverter
      {
          public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
          {           
             return "&amp;#8734;";           
          }
  
          public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
          {
             throw new NotImplementedException();
          }
      }
  </code></pre>
  
  <p>Is there any solution?</p>
