U+21CB Leftwards Harpoon Over Rightwards Harpoon

U+21CB 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 Otro símbolo 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+21CB forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “arpón hacia la izquierda sobre arpón hacia la derecha” for use in screen reading software.

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

In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. This state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but they are equal. Thus, there are no net changes in the concentrations of the reactants and products. Such a state is known as dynamic equilibrium.
