Union With Overbar

67/256

⩂ is a barred union symbol: a union sign with a line over it. The line belongs to the glyph; the notation around it supplies its precise role.

Text symbol

What ⩂ means

It marks a union operation, with the bar built into the symbol.

Unicode's math data labels it ncup and classifies it as a binary operator—a sign placed between two operands, the values or expressions it connects.

How is ⩂ different from ?

⩂ has an overbar; is the unbarred union sign.

The related symbol uses an overbar with intersection instead. The line belongs to the selected character, not a separate mark.

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.
