In relation to entropy/second order entropy, the thought is that Voynich text is far to predictable to be any natural language, so it does not matter what sort of substitution cipher you apply, and it doesn't matter what glyphs you say are what, the relationship between the glyphs is the problem.
It's fairly simple to imitate the low entropy. "repetitive monotonous text" below. The problem is that the entropy score of my text will be mostly effected by repeated "and they shall" etc, in Voynich it is more because of things like "yteedy qokeedy qokey otedy okedy". Just from that small segment I could ask you, "o, what's next?" T or K. "d, what's next?" Y and you would be right most the time, for the whole manuscript. Normal languages don't work this way and it doesn't matter if every Y is M or every T is D, it's the same problem.
To show this specifically, you can type "d" into the Voynichese website, it has 12505 matches "dy" is 6819, so over half the time we have d we have dy. "e" 14319, "ee" 4705.. and that's not to mention how things like this happen (r/m). I think you can probably see some of the greater difficulties waiting down the road. Really the alphabet could be pictures of pandas eating bamboo sticks in different ways, we would more or less still be in the same predicament once we try to read anything.
