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
