Special characters

I made a dynamic text field that loads in a html file.
When i use special characters in the html file like éüõ (stuff like that) it doesn’t show them in my flash file.

This is my script to load the html including the css file.

var styles = new TextField.StyleSheet();

theText.html = true;
theText.styleSheet = styles;

var lv:LoadVars = new LoadVars();

lv.onData = function(content) {
theText.text = content;


is there some way to make the special characters visable ?

Thanks in advance
