We'd like to use analytics cookies to understand which symbols people look up, so we know what to research next. They are not used for advertising and we set none of them unless you say yes. What we store.
The marks of ordinary life and ordinary screens: currency signs, interface icons, keyboard modifiers and the symbols that appear on a phone without anyone having been taught them.
A symbol is here when a person meets it without seeking it out. Punctuation that belongs to writing is filed under keyboard and punctuation; a mark that only appears inside a specialism is filed with that specialism, however familiar it looks.
A near-even split between common modern usage and official standardisation — many of these are formally defined in Unicode or a national standard and then used far beyond what the definition says.
