That's it. I iterate to get a H2 at around 2.1 (as the Voynich) and the same digraph statistics. By now I get the best JSD with Romeo and Juliet (0.29) but English has quite a lot of long words.

Register or Login to view.Moreover, in ciphers of the time it seems that it was common to encode digraphs like "ch" and doubled consonants like "ss" and "cc" as single letters, because otherwise they could be keys for cracking the encryption.

This is a great idea to reduce the original word length. I worked with EVA digraphs (for example "qo" to cipher one single original letter) but I think it's wort to try to encode the most used digraphs of the text in a single EVA char. 

Thank you!
