What it is and where it’s used: Neither a Superset of nor Equal To is part of the Symbols family (block: Mathematical Operators). If you need styled or decorative alternatives, try our Fancy Text tool to generate compatible text that works in most modern interfaces.

History & usage: The symbol U+2289, named Neither A Superset Of Nor Equal To, is a member of the Mathematical Operators block. It appears in some mathematical texts and software to show a relation that is not a subset or equality. In history, designers added many symbols to cover standard relations. The symbol helps clarify statements about sets and operations in formulas. Users may see it in advanced math, logic, or computer interfaces that display relations. Its name is long, but people often refer to it by its code point. In everyday math tools, this symbol is rarely the default choice; it appears where more precise relations are needed. The usage note is concise: common math symbols indicate operations or comparisons in formulas and user interfaces. This symbol fits that purpose by signaling a non-subset, non-equality relation in suitable contexts. Remember that different fonts or software may render the glyph with slight stylistic differences, but the meaning stays the same. Its role, like other operators, is to help users read and compare elements clearly in equations and UI elements.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2289 in many development tools or editors. Some operating systems provide a character viewer or input palette that lets you search by name or code and insert the glyph into documents.

Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint. Switching to a font with broader Unicode coverage or using a fallback font usually fixes the issue. On the web, ensure the page’s font stack includes a general‑purpose fallback.
