You probably can't do it (currently?) without a fixed-width font like Courier. With
a fixed-width font every letter occupies the same horizontal space, so you could
probably count the letters and multiply the result with the current font size in
ems or exs. Then you would just have to test how many letters fit on one line, and
then break it up.</p>
