What it is and where it’s used: N-Ary Union Operator with Plus is part of the Symbols family (block: Supplemental 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 N-ARY UNION OPERATOR WITH PLUS has the code point U+2A04. It belongs to the Supplemental Mathematical Operators block. The character name is provided in English as N-ARY UNION OPERATOR WITH PLUS. It is used in math contexts to show a kind of union operation with addition in larger, more complex expressions. In formulas and user interfaces, the symbol helps indicate combining several items or steps in a rule set. This use aligns with other n-ary operator ideas, where many elements join under one operation. The symbol is a mathematical tool rather than a standard vowel, letter, or punctuation mark in text. It appears in places where compact, formal notation is needed to express groupings or unions. The representation helps users recognize a structured operation in equations and formulas. The character is part of its own block and carries the conventions of advanced mathematics. It supports clear communication in technical documents and computational interfaces.
Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2A04 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.

Compatibility & troubleshooting
Font support: if the symbol does not render, the current font likely lacks this codepoint. Choose a font with broad Unicode coverage or allow a fallback font.
Web pages: ensure your CSS font stack includes a general fallback; avoid relying on images for common symbols to preserve accessibility and copyability.
