I noticed that the grove LCD screen only has an ASCII/Japanese font table. I need to be able to display accented characters looking at the data sheet the screen supports up to 8 custom CGRAM characters. I added an API to set those CGRAM characters as well as a map of common latin 1 characters + emoticons
