Unicode Version 17.0
𝝿
U+1D77F "𝝿" Mathematical Sans-Serif Bold Small Pi is a stylistic variant of the lowercase Greek letter pi, designed in a sans serif typeface with a bold weight for use in mathematical and scientific notation. It is part of the Mathematical Alphanumeric Symbols block, which provides distinct letterforms to represent variables, constants, or operators while avoiding confusion with standard text. This specific character preserves the traditional shape of pi but adopts a clean, modern appearance without serifs, making it suitable for equations where clarity and differentiation from italic or serif forms are needed.
