Galo,

You can use the following:

<TextBlock Text="Hello World &#8482;"></TextBlock>

 For a more complete list, please see the following resource:

Also, to add to this.  You can only use this syntax if you are putting the information in the XAML tag itself (also note, you cant use the special HTML characters, you must convert them all to Unicode... so your trademark would be &#8482;. 

If you need to assign the value in code, you will want to use the System.Windows.Browser.HttpUtility.HtmlDecode() method.  So if you want to set the text property of the TextBlock x:Name="Title" to Microsoft Vista™ then you would want to use the following code:

1    Title.Text = System.Windows.Browser.HttpUtility.HtmlDecode("Windows Vista™");

That will allow you to display the trademark symbol in the TextBlock at runtime. 

Furthermore, if you want to to use it in data binding... You will need to use a value converter within the Binding extension property.  So basically, your XMAL would look like this:

1    <TextBlock Text="{Binding Title, Converter={StaticResource htmlDecodeConverter}}" />

And your source code would look like this:
 

1    public class  HtmlDecodeConverter : IValueConverter
2    {
3      public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
4      {
5         return System.Windows.Browser.HttpUtility.HtmlDecode(value as string);
6      }
7    
8      public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
9      {
10        throw new NotImplementedException();
11     }
12   }

PLEASE NOTE: I typed this in, did not copy and paste, so there may be typos.  But hopefully it gives you the right idea.  You will also need to include a static resource tag at the top of your XAML and you will need to add the xmlns to your namespace.  For example, if your namespace is SpecialCharacters you will want to add the xmlns:local="clr-namespace:SpecialCharacters" and then in your UserControl:

<UserControl.Resources>
  <local:HtmlDecodeConverter x:Key="htmlDecodeConverter" />
</UserControl.Resources>

Thats about it!  Hope this answers your question!
