AS3 Bold and Italic text in dynamic text fields

Dynamic text fields in Flash CS4 don’t show Bold or Italic text for some bizarre reason. I found this out when I tried to set the character style of a dynamic text field to Italics. When I exported the movie the Italic text did not appear. I try the Bold character style and that also did not appear.

I figured out you can get around this problem by using the TextFormat class.
Here is the code I used for the Italic text.

output_txt.text='hello ilike2flash';
var ItalicText:TextFormat = new TextFormat();
ItalicText.italic=true;
output_txt.setTextFormat(ItalicText);

The code for the bold text is similar.

output_txt.text='hello ilike2flash';
var BoldText:TextFormat = new TextFormat();   
BoldText.bold=true;
output_txt.setTextFormat(BoldText);

Another solution is to use the Italic tags in the htmlText.

output_txt.htmlText = "<I>Hello</I>"

If the Bold or Italic text still does not appear in the dynamic text field. You can try embedding the fonts.
