U+21A3 Rightwards Arrow with Tail

U+21A3 was added in Unicode version 1.1 in 1993. It belongs to the block U+2190 para U+21FF Arrows in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Puntuación matemática and is commonly used, that is, in no specific script. El carácter es también conocido como z notation total injection.

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+21A3 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “flecha hacia la derecha con cola” for use in screen reading software.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In mathematics, an injective function (also known as injection, or one-to-one function ) is a function f that maps distinct elements of its domain to distinct elements; that is, x1x2 implies f(x1) ≠ f(x2). (Equivalently, f(x1) = f(x2) implies x1 = x2 in the equivalent contrapositive statement.) In other words, every element of the function's codomain is the image of at most one element of its domain. The term one-to-one function must not be confused with one-to-one correspondence that refers to bijective functions, which are functions such that each element in the codomain is an image of exactly one element in the domain.

A homomorphism between algebraic structures is a function that is compatible with the operations of the structures. For all common algebraic structures, and, in particular for vector spaces, an injective homomorphism is also called a monomorphism. However, in the more general context of category theory, the definition of a monomorphism differs from that of an injective homomorphism. This is thus a theorem that they are equivalent for algebraic structures; see Homomorphism § Monomorphism for more details.

A function f that is not injective is sometimes called many-to-one.
