Is there something wrong with Pokemon X and Y and the nickname filter?

I started the game already since the launch date and when I capture Pokemon in the wild, I always nickname the pokemon that I caught after characters from Tekken and Soul Calibur, but when I do there are some names that I'm trying to nickname my Pokemon I can't put because the game won't let me because of the censor filter. Like when I'm trying to nickname a female Pokemon Asuka as in Asuka Kazama, the game won't let me because the game considers the name Asuka a bad word or when I'm trying to nickname a male Pokemon Violet as in the alter ego of Lee Chaolan, the game won't accept the name Violet but the game instead accepts the name Lee. I can't even nickname a pokemon Viola either because of the filter. So is there something wrong with Pokemon X and Y or is the filter thinks certain words are bad and can't be put in the game? To me the name Asuka is not a bad word but the game thinks it is.
