Implications of the continuity of Currier "languages"

[Beatrice]

So, now the source text to be 'converted' is of course not a printed text, but a handwritten one.
This would mean that a text in a humanist hand could result in a different output than the same text written in a gothic hand. A source text with a variation in handwriting style could result in a variation of the output 'language'.  Even, a source text with a discontinuity in the handwriting style could cause a gradual (but fast) change in the encoding, as the encoder gradually adapts.
Different people might break up the source characters into components in different ways.

The last case would be an example where Currier-A words and Currier-B words map back to the same source text words, but perhaps not in a trivial manner.

Anyway, this can be continued ad libitum.

Hello René,

If there was a humanist hand, that would mean that the scribe had to read a printed book at the end of the 15th century (the first printed book in Italy was in 1464. In Spain the press was brought in 1472). Also we had to remember that the humanist script only became known after 1500s. Given those historical facts, I think it is completely impossible that the Voynich ms author had heard of or seen that type of writing style, only used for official documents and Classical Literature. 
If the Voynich Ms author had known or seen the humanist script, that would  necessarily involve that he worked for high-class members (as a secretary, a notary, a chancellor). For example, Poggio Bracciolini (1380-1459) or Coluccio Salutati (1331-1406)  were the first Italian to use a New Gothic Script  (a transition of Gothic cursive to a humanist style spread at the end of the fifteenth century thanks to the print press). 
Salutati's handwriting:

So I cannot see how the Voynich scribe could use what was only known to a select group of people.
