inverted lazy s

Inverted lazy S

One W3C math-entity list labels ∾ “most positive”; the meaning in an equation still depends on its author’s convention. In music notation, a sideways-S turn mark also goes by “inverted lazy S,” but that nickname does not establish it as this exact character. The reversed tilde ∽ is a separate sign.

What ∾ means

∾ is the inverted lazy s. Unicode classifies it as a mathematical symbol and files it in the Mathematical Operators block; this site shelves it under Maths.

Its appearance depends on the font and text styling.

How it is encoded

∾ is a single code point, U+223E. In HTML that is ∾, and in CSS \223E.

Don't confuse it with

∽

Reversed Tilde

∽ is the reversed tilde, a distinct character. Its similar S-like curve does not make it a variant or substitute for ∾.

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.
