On the contrary, to handle those you are going to first have to convert
to numbers otherwise you are just "substring" isn't really going to be
the right relation for roman numerals. Having converted to numbers you
could use either approach to truncate the upper range limit before
converting back to roman numerals. (You'll probbaly need a different
truncation algorithm, in this case, if you want to trucate at all).
