Character name changes

[Chopain]

So I'm playing as England and I loaded a game and I noticed that my childrens names have changed to unpronounceable non english names followed by de Normandie. So I randomly clicked on other people and noticed that most names in the game have changed. I did noticed that many historical people did keep their names.
