What are some obscure/rare/endangered/extinct typographic symbols?

Just discovered the “asterism” today:

Super cool. I had never heard of it or seen it before. Wikipedia has more about it.

What other typographic symbols are out there that were never all that popular or have fallen out of favor? What were they used for?

I placed in two that I know as a community wiki; I encourage others to build out a list.


(Unicode character U+2042 and HTML symbol ⁂ as well as Alt + 8258 on Windows)

Used to ‘indicate minor breaks in text,’ call attention to a passage, or to separate sub-chapters in a book.

Currency Symbol ¤
(Unicode character U+00A4 and HTML symbol ¤ or ¤ as well as Alt + 0164 on Windows)

Used to denote a currency when the symbol for the particular currency is unavailable.

(Unicode character U+203D and HTML symbol ‽ as well as Alt + 8253 on Windows)

Used in various written languages and intended to combine the functions of the question mark … and the exclamation mark.

Sound Recording Copyright Symbol
(Unicode character U+2117 and HTML symbol ℗)

The copyright symbol used to provide notice of copyright in a sound recording (phonogram) embodied in a phonorecord (LPs, audiotapes, cassettes, compact discs, etc.)

Commercial Minus Sign
(Unicode character U+2052 and HTML symbol ⁒)

The commercial minus sign was and is widely used in bookkeeping to indicate a minus sign. On typewriters a ./. was written instead.

to be continued … 😉
