[split] Diplomatic ciphers

[-JKP-]

JKP: What I am referring to is strings containing complex characters not ordinary letters of the alphabet, which are basically just normal words. Also I regard characters like the 4o where the characters are physically joined together as one character not a character sequence. I hope that is clearer, if not please ask.

What do you mean by complex characters? If you mean sequences of Latin abbreviation symbols, those exist too, they are just harder to paste into forum posts.

The Italian diplomatic ciphers are both many-to-one and one-to-many. There was no prohibition on a letter being represented by only one symbol/character.
