◯

A circle mark ("◯") is often used in East Asia to express affirmation. Its use is similar to that of the checkmark ("✓") in the Western world. Its opposite is the X mark ("✗" or "×"). The symbol's names and meanings vary across cultures. In Japanese it is called marujirushi (丸印) or maru (丸) and expresses affirmation. In Korean it is called gongpyo (공표; 空標; lit. 'zero mark') and expresses affirmation.
