How to recognize a the Lewis Carroll nyctographic ciphertext? (Identification)
Lewis Carroll's Nyctographic alphabet is recognizable thanks to its basic square structure, its lines at the edge of the square and its dots positioned at the corners of the square.
Any references to Charles Lutwidge Dodgson, aka Lewis Carroll, or his writings like Alice in Wonderland are clues.
Any indication or clue relating to nocturnal writing or reading, at night, in the dark (darkness / black), or blind, is noteworthy.
