Voynichese

Voynichese is the name given to the mysterious, undeciphered writing found in the Voynich manuscript, a centuries-old illustrated book. Its text features unfamiliar characters and patterns that do not match any known language or code. Linguists and cryptographers have been unable to determine whether it’s an actual language, a code, or a constructed script. The manuscript's origins, purpose, and meaning remain unknown, and Voynichese continues to intrigue researchers as one of the greatest puzzles in historical cryptography.
