Here is my version of the letter-set for the Voynich alphabet. The layout follows Mike Roe’s Generic Word.
As I will discuss later, the values turn out to be the 20-letter Latin alphabet, plus “k”. EVA q is a special case. The so-called ‘platform gallows’ are combined letter values, as are those with #15 and #16 attached.
I have also determined which ones might be used as numbers, but so far have not found any examples.
