Voynichese is a numeric cipher?

[ololololo]

freely insertable zero characters from an open list

And also about the nulls. The thing is, there's nothing wrong with them, they're not mystical or politically incorrect, and they don't affect the cipher in any way. I think if I write the word AoPoPoLoE, you'll understand what kind of fruit I'm referring to. And I don't think the nulls are a serious rule. It's more of a trick or a cleverness.
