U+21E4 "⇤" Leftwards Arrow to Bar Unicode Character

U+21E4 "⇤" Leftwards Arrow to Bar is a typographical symbol that depicts an arrow pointing to the left, with its tail ending in a vertical bar. It is often used in computing and interface design to represent a leftward tabulation or indentation function, such as moving the cursor or a block of text to the left, particularly in text editors or code environments where it pairs with the rightwards arrow to bar (U+21E5). The bar at the arrow's base signifies a stopping point or a fixed boundary, distinguishing it from a simple left arrow.
