Embedding fonts in Flash Builder is so easy as follows. However, in some cases that I have no idea, Flash Builder changes the fonts in your application. To fix that, just goto topbar Project->Clean…Then Flash Builder refreshes your project and everything is gonna be fine 🙂 This is just a reminder for myself. I’m sure, I’ll forget the fix for this issue when I exprience it again.
