History & usage: The character depicts the FULLWIDTH PLUS SIGN. It is used to show operations in formulas and in user interfaces. In formulas, it stands for addition or comparison as part of math notation. In user interfaces, it helps indicate a positive action or an added value where space is tight and the fullwidth form matches surrounding characters. This usage aligns with common math symbols that indicate operations or comparisons. Cross‑platform, the fullwidth shape may appear with different spacing, and it should be readable by assistive tech when labeled.

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.
