U+1D787 "𝞇" Mathematical Sans-Serif Bold Small Psi Unicode Character

Unicode Version 17.0

𝞇

U+1D787 "𝞇" Mathematical Sans-Serif Bold Small Psi is a typographic variant of the Greek letter psi, designed in a sans-serif style with a bold weight, primarily for use in mathematical and scientific notation. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct character forms to represent variables, operators, and constants in formal equations while avoiding confusion with ordinary text. This specific glyph allows authors to denote a bold psi symbol in plain text environments, such as in digital documents or coding contexts, where traditional font formatting may not be reliably applied. Unlike standard Greek letter psi from the Greek and Coptic block, this mathematical version is intended strictly for semantic use in specialized mathematical expressions.
