U+278A "➊" Dingbat Negative Circled Sans-Serif Digit One Unicode Character

U+278A "➊" Dingbat Negative Circled Sans-Serif Digit One is a typographic symbol representing the number 1 enclosed in a circle with a negative or inverted appearance, where the digit is typically white against a solid black or dark background, as part of the Dingbats block. It belongs to a set of ten such digits (U+278A through U+2793) designed for use in lists, bullet points, ornamental numbering, or visual indicators where a bold, sans-serif style is preferred. Unlike standard circled digits, the "negative" aspect refers to its reversed contrast, making it stand out in dark mode or high-contrast designs.
