[Solved] Restricting entering special characters in TextBox using JavaScript not working for Arabic letter

For everyone's benefit

I found this and it works very good

    <script type="text/javascript">
        var specialKeys = new Array();
        specialKeys.push(35); //#
        specialKeys.push(37); //%
        specialKeys.push(43); //+
        specialKeys.push(45); //-
        specialKeys.push(61); //=
        specialKeys.push(64); //@

        function IsAlphaNumeric(e) {
            var arabicCharUnicodeRange = /[\u0600-\u06FF]/;
            var ret;
            var keyCode = e.keyCode == 0 ? e.charCode : e.keyCode;
            var str = String.fromCharCode(keyCode);
            ret = ((keyCode == 32) || (keyCode >= 48 && keyCode <= 57) || (keyCode >= 65 && keyCode <= 90) || (keyCode >= 97 && keyCode <= 122) || (specialKeys.indexOf(e.keyCode) != -1 && e.charCode != e.keyCode)||(arabicCharUnicodeRange.test(str)));
            if (ret == false) { return false; }
            else { return true;}     
        }
    </script>
