How to display numbers in Persian letter using jQuery in ASP.Net

hi

I used belwo code to display number to persian language...

    public string toPersianNumber(string input)
    {
        string[] persian = new string[10] { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹" };
        for (int j = 0; j < persian.Length; j++)
        {
            input = input.Replace(j.ToString(), persian[j]);
        }
        return input;

    }

AND

LblTsh.Text = toPersianNumber(_dr["Phone"].ToString());

now I used below code to display remainng character into label

 <script type="text/javascript">
        $(function () {
            var i = 0;
            $('[id*=TxtSMS]').keydown(function (e) {
                var ctrlKey = 67, vKey = 86;
                if (e.keyCode != ctrlKey && e.keyCode != vKey) {
                    $('[id*=LblCount]').html($(this).val().length);
                    if ($(this).val().length % 70 == 0) {
                        i = $(this).val().length / 70;
                        $('.MessageCount').html(i);
                    }
                }
            });
            $("[id*=TxtSMS]").bind('paste', function (e) {
                setTimeout(function () {
                    $('[id*=LblCount]').html($("[id*=TxtSMS]").val().length);
                    var msgCount = $("[id*=TxtSMS]").val().length / 70;
                    $('.MessageCount').html(Math.floor(msgCount));
                }, 100);
            });
        });
    </script>

now how I can use topersiannumber metod for above label to display number of character in persian number?

Best regards
