For extra fun there was talk today on twitter about several people that have to file Japanese tax returns but have originally english names. There are many ways to convert the name to english, and different systems actaully enforce you to convert it in a different way with various limitations. This results in them having the system believe they are two people, one of who hasn't filed returns and no easy way to fix it (apparently the easiest fix is to possibly create a company?). This despite there being some kind of unique ID submitted in both systems, but that ID is not currently reconciled. Not sure 100% on the details myself but I guess the moral of that story is, duplicate checks on the name itself may not even be a guarantee of uniqueness - even assuming there was only 1 person with that name!
