Das CLDR-Projekt bezeichnet dieses Zeichen mit „Harpune nach links über Harpune nach rechts“ für die Verwendung in Screenreader-Software.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

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.
