Variant
The Miscellaneous Mathematical Symbols-B block has one variation sequence defined for a standardized variant. Variation selector-1 (VS1) (U+FE00) can be used with U+29B7 ⦷ CIRCLED PARALLEL to request a glyph where the parallel lines touch the circle.[3]
Usage
Some of these symbols are used in Z notation. Specifically
- U+2981 ⦁ Z NOTATION SPOT
- U+2982 ⦂ Z NOTATION TYPE COLON
- U+2987 ⦇ Z NOTATION LEFT IMAGE BRACKET
- U+2988 ⦈ Z NOTATION RIGHT IMAGE BRACKET
- U+2989 ⦉ Z NOTATION LEFT BINDING BRACKET
- U+298A ⦊ Z NOTATION RIGHT BINDING BRACKET
The last two symbols are used in combinatorial game theory
- U+29FE ⧾ TINY
- U+29FF ⧿ MINY
