Looks like I need to use empty string for the second parameter.

      String newValue = @"Testing
bad

chars" + (char)14 + " char(14) " + (char)12 + " char(12) " +  (char)31 + " char(31) Was the last char.";

            Console.WriteLine("{0}, Length = {1}",newValue, newValue.Length);

            StringBuilder invalidChars = new StringBuilder();

            for (int i = 0; i < 32; i++)
            {
                if (!i.InList(8, 9, 10, 13))
                    invalidChars.Append((char)i);
            }

            newValue = newValue.ChrTran(invalidChars.ToString(), "");

            Console.WriteLine("{0}, Length = {1}",newValue, newValue.Length);
