Acéré (sharpened blades)
The Acéré alphabet is a graphic substitution cipher where each Latin letter is replaced by a sharp glyph. The name comes from Latin acer (“pointed, sharp”), and that’s exactly the visual spirit: acute triangles, pointed notches, slender strokes. Distributed on the dCode platform in the Symbol Ciphers section.
It’s a stylistic cousin of our Daggers alphabet (see entry) — same “sharpened blades” imagery — but with a different correspondence table. Acéré uses combinations of triangles and notches that Daggers doesn’t, and vice versa. 26 Latin letters. No digits in the distributed version (ASCII codes 55-57 return 404 on dCode).
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext letter is replaced by a fixed Acéré glyph. The technique goes back to Antiquity (Caesar cipher, ~50 BC) — the alphabet’s originality is purely visual.
The table holds 26 glyphs for the 26 Latin letters (no digits). The glyphs are deliberately angular and pointed — the eye distinguishes them easily, which is essential for a hand-readable cipher.
Cryptographic strength: low. Like any monoalphabetic substitution, frequency analysis breaks it in a few dozen words. The alphabet is valued for its aggressive look in a medieval-themed escape room, an adventure gamebook or a fictional grimoire.

What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- Public table — available on dCode.
- No digits — to encode a number, write it out in words.
