Huh? That's a bit like saying the name "John Doe" is "perhaps best known from being the name of a character in a movie." It's just the stand-in, "generic" Japanese name that's used in examples. If an alien had the name in a cartoon it was probably a joke about the alien going out if its way to appear ordinary, the way the characters in Third Rock from the Sun were named Tom, Dick, and Harry.
Anyway, this article always kind of rubbed me the wrong way. OK, maybe someone's name is one character that's not possible to represent with Unicode. What do you want me to do about it?
