How to show a message box avoid of the bug in 'Alert'

Compatibility: Web Runtime in S60 3rd Edition, Feature Pack 2

Problem

Developing widget with javascript. It has a bug with the Alert("") in JavaScript to be shown in S60: There is a sign of unknown character '口' appeared in left upper position.

Soluton

How to avoid it? We could use below code instead of alert to show a message to user.

Code

	var uiManager = new UIManager();
	uiManager.showNotification(3000, "warning", "Input error. Try again.");
 
	//or
	uiManager.showNotification(3000, "OK", "Done successfully.");

Of course, we should include WRTkit.js which was provided by nokia to make UIManager to be known.
