U+210F "ℏ" Planck Constant over Two Pi Unicode Character

U+210F "ℏ" Planck Constant over Two Pi is a typographic symbol representing the reduced Planck constant, a fundamental physical constant that equals the Planck constant divided by two times pi. This symbol, commonly referred to as "h-bar" in scientific contexts, is used extensively in quantum mechanics to express quantities like angular momentum and the reduced form of energy quanta. Its inclusion in Unicode ensures consistent representation across digital platforms, allowing physicists, mathematicians, and engineers to accurately display this notation in documents, web pages, and technical writing without relying on custom font substitutions or mathematical markup.
