WeiDoes anyone know anything about the broken slash that sometimes appears in precomposed fractions – whether there was a clear first precedent, or if it goes back to metal?
Aaron Bell@w__h_ the first time I recall seeing it was in Recursive but I wouldn't be surprised if it predates that

@sajatype @w__h_ Recursive is definitely post IBM Plex Mono, that is shown in the sample.
Let’s ask @boldmonday, if there was a historic example for this.

Triple ⁂@eWalthert @sajatype @w__h_ not that it helps but I remember seeing it in @ohno Covik, released in 2018.

Broken fraction bars were already part of Nitti (2007) before we developed IBM Plex Mono in 2016. I guess historical examples can be found in typewriter typefaces. But Pieter @cakelab is the best person to ask about this.

Florian Hardwig@boldmonday @triple @eWalthert @sajatype @w__h_ @ohno @cakelab Here’s an example from the realm of metal type, shown by Pittsburgh Type Founders in 1918. Not a systematic approach, but definitely fractions with broken bars.
