I'm looking to implement the solution provided in this answer but it's not working. The code in this jsFiddle have looks like this:

function Start() {



    $('#TheBox').keyup(function () {



        var TheInput = $('#TheBox').val();      

        var TheCleanInput = TheInput.replace(/([.p{L}])/g, '');



        $('#TheBox').val(TheCleanInput);

    });

}



$(Start);

Basically, I'm looking to allow letters such as é è ô as well as numbers. What do I need to change to make the regex filter work?
