ITC Zapf Dingbats (Hermann Zapf, 1978)
ITC Zapf Dingbats is one of the most influential typefaces of the 20th century. Designed by the German master Hermann Zapf — already the author of Palatino, Optima and Zapfino — and published by the International Typeface Corporation (ITC) in 1978. Its catalogue holds 360 decorative glyphs: hearts, stars, arrows, pointing hands, floral ornaments, calligraphic frames.
Adobe’s master stroke: bundling Zapf Dingbats into the PostScript 1 standard in 1984, which made it available everywhere — on every PostScript printer, in every DTP application. The Unicode Dingbats block (U+2700..U+27BF), added in 1993, lifts its catalogue directly. It is today the canonical reference whenever dingbats come up. 26 letters + 10 digits + 4 punctuation marks remapped onto its glyphs.
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext ASCII character is replaced by the Zapf glyph at the same code. Strictly the Caesar cipher logic (~50 BC) — a 1↔1 table — except the “key” is a legendary typeface.
The table covers 26 letters + 10 digits + 4 punctuation marks (! ? . ,): a representative subset of the 360 Zapf glyphs. Other ASCII codes (and the full Unicode block U+2700..U+27BF) are not exposed here for consistency with the rest of the catalogue.
Cryptographic strength: low. Always the same letter → always the same dingbat. Frequency analysis breaks it in a few dozen words. It’s a prestigious and decorative alphabet, not a confidentiality tool.
Historical and modern usage
- DTP — InDesign, Quark XPress, since the 1980s.
- Print — every PostScript printer ships Zapf Dingbats.
- Unicode Dingbats — catalogue lifted straight into the standard.
- Typographic branding — book covers, exhibition posters.

- Webdings (1997) — see our entry, Microsoft web dingbats.
- Symbol (1985) — see our entry, another canonical PostScript font.
What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- Universal font — available on every PostScript printer.
- No polyalphabetism — no key, just the table.
