scream

A console application that implements the Scream Cipher from XKCD #3054.

The Scream Cipher encodes text by replacing each character with an 'A' modified by diacritic marks. This ensures all messages appear as a string of 'A's while still carrying the original meaning.

Features

✔ Encode text into the Scream Cipher.
✔ Decode Scream Cipher text back into ASCII.
✔ Cross-platform compatibility when compiled for the target system.
✔ UTF-8 support for proper diacritic display.
