    Using the restrict property for a textfield - \u is not working?

    BIOSMonkey

      I am trying to set a numeric code range (versus entering string characters) for the restrict property of a text field.  The documentation states that this can be achieved via the unicode escape sequence, such as "\u0030-\u0039".  But I cannot get this to work. 

       

      Even trying single character such as

       

      <mx:TextInput id="tt" width="100%" restrict="\u0030"/>

       

      is failing. As I understand it, this should only allow the number 0 to be entered, but it does not work.  Instead, I am able to enter 0, 3, and u, so the \u seems to be ignored.

       

      Am I missing something simple?
