Superset of with Not Equal To ⊋
⊋ (U+228B) is a standard Unicode character that you can copy and paste anywhere text is accepted. This page provides a concise reference with safe tips, internal links, and practical guidance so you can use it reliably across apps and platforms.
What it is and where it’s used: Superset of with Not 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+228B, named SUPERSET OF WITH NOT EQUAL TO, belongs to the Mathe matical Operators block. It is used mainly in mathematical notation to show a relation between sets. In formulas, it can indicate that one set is a superset of another with a not equal condition. This helps express ideas about inclusion and difference in one symbol. In practice, writers may combine it with other symbols to form precise statements about set relations. The character appears in math texts and in software that supports mathematical notation. It helps convey a relation that is stronger than a simple not equal while still involving a superset idea. When people type formulas in user interfaces, the symbol guides readers to understand how collections relate. The provided usage context notes that common math symbols indicate operations or comparisons in formulas and user interfaces. As a result, the symbol is useful for formal logic, proofs, and technical documents. It is defined in the common block for symbols and carries clear meaning for those who read advanced math.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+228B 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.
