Ok, I’ve finally extracted all the capital letters (for now) and now I have the fonts.

What I was doing wrong: While working on the Radial Menu, I had each action as an "img", which limited the game to be in French only.

What I can achieve now: With the fonts extracted, I can translate the menu options and everything written in capital letters. 

What’s left to do: Some letters are still missing... I might need to recreate those myself.
