Is it possible to embed fonts at runtime to use for existing dynamic textfield instances in SWFs?

I'm trying to embed fonts at runtime in actionscript and it somewhat works. I can embed fonts by either using the embed tag or by loading a font library asset with a linkage name and use it with a new TextField. However, a textfield that exists on a movie clip already does not have the embedded font and is missing characters.

A quick example in code (textInstance exists on the movieclip):

var embeddedFonts = Font.enumerateFonts(); //Shows embedded font

var textFormat:TextFormat = textInstance.getTextFormat();

textInstance.text = "Don't be lazy"; //missing characters 

var textField:TextField = new TextField();

textFi开发者_运维百科eld.embedFonts = true;
textField.defaultTextFormat = textFormat;
textField.selectable = false;
textField.autoSize = TextFieldAutoSize.LEFT;
textField.multiline = true;

textField.text = "Don't be lazy"; //shows all characters
addChild(textField);

Is it possible to do this? I want to embed the font at runtime and I'm loading multiple SWFs and I don't want to embed the font in each SWF.

I assume you have textInstance already added to your swf and it has a TextFormat with the font you are loading later.

After loading your font into your swf you should either set the text again with textInstance.text = textInstance.text (if textInstance has a defaultTextFormat) or set the textFormat with textInstance.setTextFormat(textFormat), because the textfield doesn't update automatically upon loading a font.

I had to create a new TextFormat with the font and set it as the defaultTextFormat in order to get it to work.
