Wingdings 3 (Microsoft, 1995)
Wingdings 3 completes the Microsoft dingbat family (Bigelow & Holmes, from Windows 95 onwards) with a thematic specialisation: every ASCII slot contains an arrow. Single or double points, straight or curved, triangular or chevron, open or filled — the set covers every typographic arrow used in schematics, diagrams and wireframes.
It’s typically the font Windows users opened in 1998 when they wanted to drop a “big arrow” into a Word document or a PowerPoint slide, back when the dedicated Unicode blocks (U+2190..U+21FF, U+2900..U+297F) were not yet well supported. Like its two siblings, it stayed installed by default on every Windows for a quarter of a century.
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext ASCII character is replaced by the arrow the font displays at the same code. Same logic as the Caesar cipher (~50 BC) or Wingdings 1 / 2: a 1↔1 table, here made of directional glyphs.
The table covers 26 letters + 10 digits + 4 punctuation marks (! ? . ,). Arrows are organised by families: codes 33-64 → simple arrows, 65-90 → double/framed arrows, 97-122 → curved or triangular arrows.
Cryptographic strength: low. Monoalphabetic substitution = trivial frequency analysis. The point is purely graphic: a ciphertext looks like a logistics chart or a battle plan, which works very well in a teaching aid or an escape room.
Historical and modern usage
- Word / PowerPoint diagrams — illustration arrows at large size.
- Graphic wireframes — UI directional stars.
- Escape rooms — “mission plan” framing of a coded message.
- Pedagogy — example of a thematic typographic substitution.

What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- Public font — installed by default on every Windows.
- Close-looking glyphs — some arrows differ only by stroke thickness.
