U+20D6 "⃖" Combining Left Arrow Above Unicode Character

U+20D6 "⃖" Combining Left Arrow Above is a combining diacritical mark designed to be placed over a preceding base character to indicate a leftward pointing arrow in mathematical, phonetic, or other technical notation. As a combining character, it does not occupy its own horizontal space but instead overlays the glyph to its left, typically used in vector notation to represent a leftward direction or a retracted articulation in linguistics. This character is part of the Combining Diacritical Marks for Symbols block, where it serves alongside other arrow combining marks to provide precise directional annotations in text without altering the base character's spacing.
