I think there's a translation error here: I want to read the width of the characters. (Google translated :-))
I can determine the size of the characters. With FreeFonts, not all characters are the same width. An "i" is narrower than an "M".
Since I want to split my screen into two areas, the left part should not write in the right part. If I can read the width of the characters, I know when to start a new line.
