Problems with Ñ and accents while editing flash template

Hello

Please, someone help!

I have been trying to edit the text of a flash template and when i publish it, i cant see the Ñ and the accents

i have been looking for a solution and i have found over the internet:

system.useCodepage = true;

But that does not work, i still cant see that symbols when the file is published.

this is a dynamic generated text from code inside the fla. i am using cs5.

here is the code i have in the template:

var menu_label:Array = new Array("BIENVENIDO", "DISEÑO GRAFICO",
                                 "DISEÑO WEB", "PORTAFOLIO",
                                 "PUBLICIDAD ON-LINE", "IDENTIDAD CORPORATIVA",
                                 "REGISTRO DE DOMINIOS", "CONTACTO",
                                 "ALOJAMIENTO WEB" );
var total:Number = menu_label.length;
var i:Number = 0;
var page:Number;
var main_menu:MovieClip = new MovieClip();
stage.addChild(main_menu);

for( i = 0; i < total; i++ )
{
    var btn = new flashmo_button();
    btn.name = "flashmo_btn" + i;
    btn.scaleX = btn.scaleY = btn.alpha = 0;
    btn.item_no = i;
    btn.flashmo_bg_color.gotoAndStop( i + 1 );
    btn.flashmo_click_area.addEventListener( Event.ENTER_FRAME, btn_enter );
    btn.flashmo_click_area.addEventListener( MouseEvent.ROLL_OVER, btn_over );
    btn.flashmo_click_area.addEventListener( MouseEvent.ROLL_OUT, btn_out );
    btn.flashmo_click_area.addEventListener( MouseEvent.CLICK, btn_click );
   
    var each_substring:Array = menu_label.split("|"); 
    btn.flashmo_button_label.fm_label.text = each_substring[0]; 
    btn.item_url = each_substring[1];
    btn.flashmo_button_number.fm_number.text = ".0" + ( i + 1 );
    main_menu.addChild(btn);
}

function btn_over(e:MouseEvent):void
{
    e.target.parent.over = true;
}

function btn_out(e:MouseEvent):void
{
    e.target.parent.over = false;
}

function btn_click(e:MouseEvent):void
{
    var mc = e.target.parent;

    if( mc.item_url != undefined )
        navigateToURL( new URLRequest( mc.item_url ), "_parent" );
    else 
        change_page(mc.item_no);
}

function btn_enter(e:Event):void
{
    var mc = e.target.parent;
    if( mc.over == true )
        mc.nextFrame();
    else
        mc.prevFrame();
}

function change_page(no:Number):void
{
    page = no + 1;
    play();
}
