Register or Login to view., tiThe second type is where some plaintext letters map to a single glyphs, while some map to 2-(or 3- or more glyph combos -- so plaintext 'C' might map to Currier "OP", while plaintext 'K' might map to Currier "P". A straddling checkerboard is a (from the point of view of the C-14 date somewhat anachronistic) cipher of this type (You are not allowed to view links. Register or Login to view. shows examples). The problem this raises is that if you have "CLOCK" as a plaintext word, then the "CK" at the end would result in "OPP" in the Voynich text given the hypothetical mappings -- and except for Currier 'C', repeated glyphs vanishingly rare -- out of 35483 digrams in (D'Imperio's) BioB, there are 15 that are doubled glyphs other than "CC". So either there just miraculously happens to be a natural language whose letter contact stats allow a mapping that avoids that problem, or there is some mechanism in the cipher that hides such doubled glyphs -- perhaps the difference between Currier "OF" and "OP" isn't that they map to different plaintext letters, perhaps "OF" is what you write where "OPP" would otherwise occur. Or maybe the verbose cipher theory is just fundamentally wrong...You are not allowed to view links. Register or Login to view., this cipher is very interesting. Consider that someone doesnt know what arabic numbers are, thinks that glyphs of this chiper are 1,2,3,4,5,6,7,8,9,0, and make entropy analysis based on them. What will be the result? A low entropy compared with a natural language.
Consider other options, like adding nulls, repeated letters in plain text, to say hello heeello or hehello, and homophonic sustitutions.
There is a wide variety of options to deal with.
