"nroff" uses a table for each supported terminal type that contains
character sequences needed for a variety of functions.  It also
describes the width of each individual character, so at least in
theory it can support proportional printing.  However, its horizontal
spacing is done by a combination of space characters and "plot mode"
escapes.  There is a "narrow space" character but that's it.
