Scream Cipher: A Novel Use of Unicode Characters

This article introduces a fun cryptographic algorithm – the "Scream Cipher" – that leverages the numerous variations of the Unicode character 'A' to encrypt text. A simple dictionary mapping substitutes standard letters with different 'A' characters for encryption and decryption. Python code demonstrates the algorithm's implementation, successfully encrypting and decrypting the sample text "SCREAM CIPHER." This showcases the richness of the Unicode character set, offering a unique, albeit simple, encryption method.
