I think there's some exception we have to add here for newline
characters, because they are treated as GLYPHLESS_DISPLAY_THIN_SPACE or
as GLYPHLESS_DISPLAY_EMPTY_BOX with a width of 1 space, but I am not
sure what the best way to do this would be. Maybe Eli has a good idea
of how this can be fixed?
