My given name includes a generational suffix (a roman numeral); my home state, upon issuing a drivers license, wrote that out as an arabic ordinal numeral. E.g., instead of "III" for "the third", I got "3RD". On an official government ID.

I eventually moved, and every state after that wasn't quite that dumb.

Needless to say, this matches nothing at all, like airline tickets, or my birth certificate or passport. Shockingly, this was never a problem.
