can be used for chats click "see inside" right click and export on the sprite and for importing click "add sprite" "upload" and choose the file you downloaded you can add more letters or symbols if you'd like just add it as a costume on the sprite :)
this uses costumes and costume numbers basically when you switch costume it will change it to the exact letter you give it then i get the costume number and boom you just translated it! now you can add more symbols as it doesn't have all of them i added basic ones like !",.)(-_ now if you use a font make sure all the letter and symbols code match
