LEFT RIGHT ARROW

About this character

U+2194, the left right arrow, is a typographic symbol representing bidirectional horizontal movement or relation. It commonly indicates mutual influence, equivalence, or a reversible process in mathematics and technical writing, often replacing phrases like “corresponds to” or “in exchange with.” In programming contexts, it may denote two-way data flow or a toggleable direction in diagrams and interface annotations. As part of the Unicode Arrows block, it inherits a long tradition of arrow notation rooted in ancient directional markers and mid-20th-century mathematical formalism. In design and typography, its balanced, dual-pointed form makes it ideal for showing negotiation, alternation, or cyclic exchange between two points.
