Problem, Japanise and Chinesse Characters are not showing in screen

Hi

I´m building an App for iPhone with Flash CS5.5, I'm trying to make it in several languages, but I can't get the Chinese or Japanese showed in screen

I use a Dynamic field, with Font Arial, (which I've embedded all the fonts), this field is fill with a value in an array depending in which language the user is working

The Array looks like this:

var ArrayMy:Array = new Array("Hola","Hello","間格","間の")

I put the value in the dynamic text field in this way

DynamicField.text=ArrayMy[WKlanguage]

Works fine in every language, like special characters in french, Dutch, but Chinese and Japanese show nothing... Is there any way to get this working, Am I loosing something?

Thanks
