U+27C8 "⟈" Reverse Solidus Preceding Subset Unicode Character

Unicode Version 17.0

U+27C8 "⟈" Reverse Solidus Preceding Subset is a mathematical symbol used in formal notation, particularly within set theory and logic, to represent a specific relational or structural connection where a reverse solidus (a backslash-like element) precedes a subset symbol. Unlike the more common subset or superset operators, this character combines two distinct visual components to denote a specialized operation or condition, such as indicating that a set is a subset of another after applying a set difference or complement function. It belongs to the Miscellaneous Mathematical Symbols-B block and is intended for use in advanced mathematical typesetting where precise symbolic encoding of complex relationships is required, offering a single character representation for what might otherwise be expressed with multiple separate glyphs.
