LEFTWARDS ARROW

About this character

U+2190, commonly known as the leftwards arrow, is a fundamental typographic symbol denoting direction, movement, or causation pointing left. Originating from early computer character sets and standardized in ISO 8859-1 and Unicode, it descends from mathematical notation for mapping functions and logical implication. In programming, it appears in pseudocode, assembly instructions, and comments to indicate assignment or flow. Designers use it for navigation, back buttons, or UI affordances, while writers employ it in diagrams, user guides, and process flows. Its simplicity makes it a universal visual cue for reversion, retreat, or backward progression, distinct from longer or variant arrows. This glyph remains essential across digital interfaces and technical documentation.
