OLD-STYLE ROMAN NUMERALS (AKA "BACKWARDS-C" NUMERALS")

If your Roman numerals look odd, they probably are "Old Style," also called "backwards-c" numerals, a combination of forward and backward facing letter "c"s combined with "I" like this .  If this is what your numerals look like, consult the Text Creation Partnership help page:  https://textcreationpartnership.org/docs/dox/rnums.html
