How to display one animation for multiple image targets?

I want to display 1 particular animation for the same image of a different kind. For example, I want to display a animation for alphabet 'A'. But the alphabet(A) can be in many different fonts like one in Century Gothic and other is in Century Schoolbook. No matter what the font is if it's an 'A' then just show that particular animation. It can be done by putting every font in the vuforia library but that would be very inefficient. Can I implement OCR here like first I check it's actually an A or not then trigger that particular animation for it? Any suggestion will be appreciated!
