javascript - Using HTML Entities within Angular strings

Given a string in my $scope model which contains an HTML entity, how do I ensure that the entity is properly displayed as an HTML character rather than a literal string?

<!DOCTYPE html>
<html>

  <head>
    <script data-require="angular.js@*" 
            data-semver="1.2.13" 
            src="http://code.angularjs.org/1.2.13/angular.js"></script>

  </head>

  <body>
    <div ng-controller="htmlChar">{{title}}</div>

    <script>

      angular.element(document).ready(function(){

        var app=angular.module("app",[]);
        app.controller("htmlChar",function($scope){
          $scope.title = "&copy; Acme";
        });
        angular.bootstrap(document, ['app']);

      });

    </script>

  </body>
</html>

You do not need $sce to bind to strings with html. All you need is to inject ngSanitize into your app (it is not a core module), and then use the ng-bind-html attribute directive.

JavaScript

var app = angular.module('app', ['ngSanitize']);

app.controller('MainCtrl', function($scope) {
    $scope.title = '&#189; Cookies &amp; <span class="cream">Cream</span>';
});

Html

<div ng-bind-html="title"></div>
