U+1D74D "𝝍" Mathematical Bold Italic Small Psi Unicode Character
Unicode Version 17.0
U+1D74D "𝝍" Mathematical Bold Italic Small Psi is a typographic variant of the Greek letter psi (ψ) designed for use in mathematical and scientific notation, where it often represents wave functions in quantum mechanics, the digamma function in mathematics, or the golden ratio conjugate in certain contexts. It belongs to the Mathematical Alphanumeric Symbols block, which was introduced in Unicode 3.1 to provide distinct, style-specific glyphs for letters so that authors can clearly denote variables, operators, and constants without relying on font formatting. This particular character combines a bold weight with an italic slant, making it visually distinct from its plain, bold, or italic counterparts and ideal for emphasizing a specific symbolic meaning in equations or technical documents.
