Unicode Version 17.0
𝛏
U+1D6CF "𝛏" Mathematical Bold Small Xi is a typographic representation of the Greek letter xi in a bold weight, intended for use in mathematical and scientific notation where a distinct, heavy style is needed to differentiate variables, constants, or other symbolic elements within equations or technical documents. It belongs to the Mathematical Alphanumeric Symbols block, which was encoded to allow mathematicians and publishers to clearly represent algebraic expressions and formulas without relying on font-specific styling that might not render consistently across different systems or software.
