Lo siento, I didn't look. It is katakana. But you still haven't answered what your official source is. I could probably grab my copy of of the anthology and look up which characters are used for their names myself.

The reason why I asked in the first place is I was thinking it could be added to a section of an article describing the Japanese dub. Over all though, I think it just isn't necessary.
