I'd have to check with the EVA alphabet. In Frogguy 
that would be <8aiiig> (from memory) and <ig>
represents a single letter starting with an i-stroke.

A polyalphabetic cipher destroys the patterns of the
plaintext. Voynichese being full of strict patterns
I doubt that it is a polyalphabetic cipher. The only
possibility I can see is that some chunks are 
enciphered with one simple-substitution cipher,
others with a second simple-substitution cipher,
thus giving "Language" A and "Language" B.
