History & usage: The character Infinity negated with vertical bar (U+29DE) belongs to the Miscellaneous Mathematical Symbols-B block. It is a specialized math symbol used in some formulas and interfaces. The symbol can appear in contexts where a relation or operation is shown with a negated form. In practice, it may indicate a restricted or modified infinity concept in certain diagrams or proofs. The name helps scholars and students reference the character without fear of misreading. Fonts and math editors may render the symbol with a vertical bar crossing the shape that suggests negation or exception. While not as common as basic operators, it fits into a family of symbols used to express nuanced relations. Its use depends on the font and software, so you may see variations in appearance. The key point is that it conveys a distinct, specialized meaning beyond standard infinity. Common math symbols indicate operations or comparisons in formulas and user interfaces. This helps users recognize when a symbol is part of a larger notation system rather than a standalone glyph.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+29DE 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.
