Note that there are precomposed codepoints for ligatures of 3 ASCII
characters as well, for example U+FB03 LATIN SMALL LIGATURE FFI.

Would it be good enough to have a command that will arrange for these
ligatures to be displayed as their ASCII equivalents, using the
facilities in latin1-disp.el? Such a command could be invoked either
manually or from your init file. latin1-disp.el also provides a
special face to display such equivalents, so you could have them stand
out on display if you want.
