Square Image Of is a formal mathematical operator or relation symbol used in academic and technical writing — algebra, calculus, logic, or set theory — to express a precise mathematical relationship concisely.
Unicode block: Mathematical Operators (U+2200–U+22FF). This large block standardizes the symbols used across algebra, calculus, logic, and set theory, replacing the inconsistent, often hand-drawn notation used before digital typesetting.
At Unicode code point U+228F (decimal 8847), Square Image Of is the 144th of 256 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, like most characters outside the 0–255 legacy codepage range, it has no dedicated Alt-code or single-key shortcut on Windows or Mac, so copy-paste is the standard, universal method for typing it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.
💡 Good to know: Not all fonts render the full math-operator block correctly — technical documents commonly specify a math-specific font (like Cambria Math or Latin Modern Math) for reliable rendering.
