upper right or lower left curly bracket section

Right Moustache

⎱ is the right moustache, a curly-brace piece used to enclose tall math. It forms one side of a pair, so alone it does not make a complete brace.

What ⎱ means

Pair it with ⎰ around tall mathematical material. The two marks form a curly delimiter around a matrix (a grid of values) or a formula written in separate cases. The nickname “right moustache” describes its curved shape; alone, ⎱ is just the closing side, not a full brace pair.

An early printed curly brace appears in Gregor Reisch’s Latin textbook Margarita Philosophica (“Philosophical Pearl”) in 1503. It groups information into a hierarchy, and the surviving brace seems to have been cut by hand for that setting. Mathematical writing later used full braces to group expressions, describe sets, and separate cases; ⎱ is a separate typesetting piece for drawing one side of a tall brace.

Technical typesetting; in ordinary prose it reads as a stray punctuation mark.

Use ⎱ only as the closing side; a whole brace needs its matching partner.

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.
