[split] Diplomatic ciphers

[Mark Knowles]

JKP: You say they have completely different structures, but that may well superficially appear so. You definitely can't say it is not an "atypical" diplomatic cipher as I have described. Imagine the scenario where each "voynich word" should be substituted by a letter of the alphabet and most spaces removed, then that would be a substitution cipher and you can't prove that is not the case. I am not saying that we have that form of extreme substitution cipher, but it would be a counterexample to your argument. I don't think this is the only possible counterexample.
