U+3299 "㊙" Circled Ideograph Secret Unicode Character
Unicode Version 17.0
U+3299 "㊙" Circled Ideograph Secret is a CJK (Chinese, Japanese, and Korean) symbol consisting of the kanji or hanzi for "secret" (秘) enclosed within a circle, and it is officially part of the "Enclosed CJK Letters and Months" block. In East Asian contexts, particularly in Japan and China, this pictogram is commonly used as an ideographic indicator to mark information, items, or content as confidential, classified, or private, often appearing on official documents, packaging, or digital interfaces to denote secrecy or restricted access. Its design and function are directly related to the concept of a "secret" stamp or label rather than representing a spoken word, making it a visual shorthand for privacy and discretion in textual communication systems.
