Answer 1

I was able to handle it by using the textArea changingHandler to allow only certain characters:

if (event.operation is PasteOperation)
    {
        event.preventDefault();
        var txt:String = Clipboard.generalClipboard.getData(ClipboardFormats.TEXT_FORMAT).
                        toString().replace(/[^A-Za-z0-9\s$%&*!@-_().]/ig, "");
             ......
    }
