U+2471 "⑱" Circled Number Eighteen Unicode Character
Unicode Version 17.0
⑱
U+2471 "⑱" Circled Number Eighteen is a precomposed typographic symbol representing the number 18 enclosed within a circle, part of the Enclosed Alphanumerics block (U+2460 to U+24FF) that was introduced in Unicode version 1.1. It is commonly used in East Asian contexts, particularly in Japanese and Korean writing systems, for numbering items in ordered lists, indicating a sequence in formal documents, or marking stepwise instructions where a clear, visually distinct numeral is preferred over inline parentheses or periods. The symbol is typically rendered as a single glyph, ensuring consistent spacing and alignment in text, and it serves as a convenient alternative to composing an 18 with a circle manually.
