It looks like the ⍼ saga has finally ended!

The unicode character '⍼' was a mystery first noticed in 2022: ionathan.ch/2022/04/09/angzarr. It's in the Unicode standard as a mathematical symbol. But no one could find any examples of it having been used, and no one knew what it represented. It was like the only record of an extinct species, fossilized in the Unicode standard.

But now someone has found the document it originally came from! It represents the angle 'Azimuth', and the symbol probably comes from the path light takes through a sextant. ionathan.ch/2026/02/16/angzarr

(@johncarlosbaez might appreciate this symbol!)
