⧦

gleich stark

Equally Strong

⧦ is a mathematical relation sign glossed “tautological equivalent”: it relates statements that have the same truth value in every case, rather than marking ordinary numerical equality. A 2001 proposal placed it among relation signs, and a 2003 Unicode math report also listed it, but neither gives a worked formula; its exact use depends on the surrounding notation.

Questions people ask

Why does ⧦ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
