It use to be a person could have an apostrophy, space, or hyphen in their name. It seems since the induction of the name changing system these characters have been removed from the table of accepted characters in a name.
I'd like to suggest that these characters be again made available in the Surname field as they once were. One of each of these characters available for the surname. So people with surnames like von Velt, Sutter-Hamillton, or La'Jeanoux can have their appropiate puctuation or space seperation.
