U+2ACF "⫏" Closed Subset Unicode Character
Unicode Version 17.0
⫏
U+2ACF "⫏" Closed Subset is a mathematical symbol used in set theory and logic to denote a subset relation that is explicitly closed, often indicating that one set is a subset of another within a closed or bounded context such as a topological space. It visually resembles a subset symbol (⊂) but with a horizontal line through it, aligning with the notation for a closed subset in topology where the subset includes its boundary points. This character is part of the Supplemental Mathematical Operators block, providing a specific and unambiguous representation for scholarly or technical writing where clarity between open and closed subsets is essential.
