AngularJS: html special characters are not showing -

I am trying to display a string in my model that represents the html of a particular character. Unfortunately, this does not show the actual character, and I do not know how to do it ...

This code is:

    
 This output is:  
  Hello, Superhero & amp; Lt;! & Lt;   
   
 
 
 You can use:  
  & lt; Div ng-controller = "MyCtrl" ng-bind-html-unsafe = "Hello, '+ namea" & gt; & Lt; / Div & gt;
