Notes 1.^ As of Unicode version 16.0

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
