U+1D6BE "𝚾" Mathematical Bold Capital Chi Unicode Character
Unicode Version 17.0
𝚾
U+1D6BE "𝚾" Mathematical Bold Capital Chi is part of the Mathematical Alphanumeric Symbols block, designed for use in scientific and mathematical notation where a bold, uppercase Greek letter chi is required for differentiation from standard text. It represents the 22nd letter of the Greek alphabet in a bold typeface, often employed in fields like physics, engineering, and statistics to denote variables, constants, or specific terms such as chi-distributions or chi-squared tests. This character is distinct from the regular Greek capital chi (Χ) in the basic Greek block, ensuring precise typographic rendering in mathematical contexts.
