Unicode Version 17.0
𝟢
U+1D7E2 "𝟢" Mathematical Sans-Serif Digit Zero is a stylized numeral zero designed for use in mathematical and scientific notation, where its sans-serif appearance helps distinguish it from the letter O and other similar glyphs. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct typefaces like bold, italic, and sans-serif for digits and letters to avoid ambiguity in formulas and variables. This character is often employed in contexts such as computer science, physics, and advanced mathematics to ensure precise rendering in plain text or digital documents when a sans-serif zero is required. Its inclusion in Unicode supports cross-platform consistency for technical and educational materials.
