Open Superset ⟄

Usage snapshot:

• Used in content written with the Common script; suitable for UI labels and body text.
• Appears in the Unicode block Miscellaneous Mathematical Symbols-A.

History & usage: The character depicts OPEN SUPERSET. The token OPEN signals an operator or delimiter role in formal notation, while SUPERSET signals a relation of inclusion or extension between sets. In general terms, tokens like OPEN or CLOSE indicate action or boundary, and tokens like MARK or RELATION can hint at how elements relate; the idea behind such tokens is to guide interpretation and spacing in typographic formulas or educational diagrams. This symbol appears in the Common script and is part of the Miscellaneous Mathematical Symbols-A block, so it commonly surfaces in scholarly texts and teaching aids that present set theory, logic, or mathematical notation. Practical uses include: documenting historical editions that annotate set relations in archival transcriptions; illustrating definitions in dictionaries or grammars where examples compare supersets to their bases; and providing compact UI cues in quick calculators or operations panels to denote a superset relation or a boundary within a formula. If cultural_capsule were present, a verbatim sentence would appear here; otherwise, use remains generic and context‑appropriate. Cross‑platform rendering is generally stable, and assistive tech can announce the token and its relation clearly.
