Enables Typekit to be embed inside of CK Editor Field.

typekit-ckeditor.js

var typkitID = 'XXXXXX';

CKEDITOR.on(
   'instanceReady',
   function(ev) {
      var $script = document.createElement('script'),
         $editor_instance = CKEDITOR.instances[ev.editor.name];

      $script.src = '//use.typekit.com/'+typkitID+'.js';
      $script.onload = function() {
         try{$editor_instance.window.$.Typekit.load();}catch(e){}
      };

      $editor_instance.document.getHead().$.appendChild($script);
   }
);

Remember to flush your browser cache after putting this in;) Thanks did the trick even with 4.x
