z notation right image bracket

Z Notation Right Image Bracket

In Z notation, ⦈ is the right relational-image bracket: it closes an expression for the image of a set under a relation—the values linked to members of that set. Its matching opener is ⦇. Z notation took shape at Oxford in late 1970s work on formal methods—using mathematics to specify and reason about software systems.

What ⦈ means

It gathers the values linked to members of a set. A relation is a collection of pairs connecting one value to another. The relational image keeps the values paired with any member of the starting set; ⦇ and ⦈ mark the expression's two ends.

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.
