U+21FA "⇺" Leftwards Arrow with Double Vertical Stroke Unicode Character
Unicode Version 17.0
⇺
U+21FA "⇺" Leftwards Arrow with Double Vertical Stroke is a typographic symbol and arrow variant found in the Arrows block, representing a leftward pointing arrow that features a double vertical line across its shaft, unlike the single vertical stroke of its more common counterpart U+21E0. This character is often used in technical notation, mathematics, or diagramming contexts to indicate a distinct form of leftward movement, direction, or mapping, where the double vertical stroke may signify a forced stop, a conditional constraint, or a specific type of blocking or inversion in user interfaces and formal logic systems.
