History & usage: The symbol U+29B3 is called the Empty Set with Right Arrow Above. It belongs to the Miscellaneous Mathematical Symbols-B block and is used in specialized math contexts to show a relation that combines an empty set with an arrow above. In history, such symbols emerged from the need to express complex ideas compactly, using small, distinct marks. The name helps identify its purpose when reading texts that cover set theory or logic. In practice, you will see it in mathematical notation where a direction or flow is implied alongside an empty set, indicating a move or mapping that yields no elements. Arrows commonly indicate direction and navigation cues in interfaces and documents. This general usage idea can guide readers to understand how arrow marks help explain movement, choice, or result in a visual field. While the exact symbol is specialized, the concept of combining a zero-sized set with an arrow clarifies a passive or empty directional outcome in formulas and diagrams.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+29B3 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.
