title: How to use Segoe UI symbol in XAML
body: <p>Seems like an easy one, but I can't figure out how to do/use <a href="http://msdn.microsoft.com/en-us/library/windows/apps/jj841126.aspx#scroll_bar_arrows">these</a> symbols.  I want to use a U+E135 symbol and I can't figure out how to do it.  Can someone give me a TextBlock example and also explain how I go about getting the hex equivalent to use in XAML.  Thanks.</p>
