Copy the generated 5-bit Baconian ciphertext.
Bacon's cipher is a steganographic method of message encoding developed by Francis Bacon in 1605 where each letter is represented by a 5-character sequence of two symbols (A and B).
It was hidden in plain sight using two slightly different typographic fonts (e.g., normal typeface for 'A' and italic/bold for 'B').
