U+21AA Rightwards Arrow with Hook

U+21AA was added in Unicode version 1.1 in 1993. It belongs to the block U+2190 to U+21FF Arrows in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+21AA forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “left arrow curving right” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: arrow.

This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Glyph for U+FE0F Variation Selector-16: ↪️ See the Emojipedia for more details on this character’s emoji properties.

The Wikipedia has the following information about this codepoint:

In mathematics, and especially in category theory, a commutative diagram is a diagram such that all directed paths in the diagram with the same start and endpoints lead to the same result. It is said that commutative diagrams play the role in category theory that equations play in algebra.
