Tuple Ciphers (Enciphering a letter with two letters)

I read about reconstruction of an interesting cipher (1537-1547) in a paper by Lasry, Simonetta, and Biermann in HistoCrypt 2025. It enciphers a letter with two letters, while enciphering a syllable with a letter. Moreover, frequent omission of the dot to distinguish syllables makes it look polyphonic. My new short article "Tuple Cipher -- Enciphering a Letter with Multiple Letters" focuses on the aspect of enciphering a letter with multiple symbols.
