History & usage: SUBSET OF ABOVE NOT EQUAL TO is a symbol from the Supplemental Mathematical Operators block. It is used to describe a relationship where one set is contained in another, but not equal. The symbol can appear in formulas and in user interfaces that show options or constraints. It fits with other common math symbols that indicate operations or comparisons. In practice, writers use it when models or rules need a strict subset relation. It helps distinguish a contained case from equality. The symbol is part of the Common script group, and it reflects standard math notation. Fonts and rendering can affect its appearance, but the idea remains the same across contexts. People may see it in educational materials, technical documents, or software that handles set theory or logic. As a tool, it communicates a precise relation without extra words. Overall, the symbol serves as a clear indicator of a strict subset relation in both static formulas and dynamic interfaces. Its use aligns with the goal of concise, precise communication in math and UI design.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2ACB 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.
