U+1F8B5 "🢵" Negative Squared Upwards Arrow Unicode Character

U+1F8B5 "🢵" Negative Squared Upwards Arrow is a typographic symbol that represents a square-shaped arrow pointing upward, with the word "Negative" in its official name indicating that it is typically rendered as an outline or hollow form rather than a filled solid shape, distinguishing it from the more common upward arrow variants. Introduced in Unicode version 7.0 as part of the Supplemental Arrows C block, this character is designed for use in technical diagrams, user interface mockups, or mathematical notation where a distinct empty upward arrow within a box is needed to convey direction without implying a filled area. Its visual appearance relies on the font rendering specifications of the system, and it is rarely included in standard fonts, often requiring specialized symbol sets or Unicode-compliant software to display correctly.
