Using font creator, is it possible to do this :
- I have an already made font (.ttf)
- I want to add to this ttf a new glyph taken from a png image i have (an emoji icon)
- Save this font in a way i can use it under android (CBDT)
You're wasting your time posting here about this. FontCreator cannot use a PNG to make colour fonts. Maybe one day, but for now at least, you need to look elsewhere.
