U+27E8 "⟨" Mathematical Left Angle Bracket Unicode Character
Unicode Version 17.0
⟨
U+27E8 "⟨" Mathematical Left Angle Bracket is a typographic symbol used primarily in mathematical notation to denote the opening delimiter of an angle bracket pair, commonly representing vectors, inner products, or averaging operations in fields such as linear algebra and physics. It is explicitly distinct from the similar-looking ASCII less-than sign "<" or its HTML entity equivalents, as it is designed to pair symmetrically with its right-angle counterpart U+27E9 to ensure proper spacing and semantic clarity in complex mathematical expressions. This character also finds use in programming languages and markup systems that require specialized bracket syntax.
