IDS Unary Operator - No
No is the designation for characters that do not function as IDS Unary Operators, meaning they are not used in Ideographic Description Sequences to denote a single unencoded ideograph via a shorthand notation. This value applies to the vast majority of Unicode code points, including all letters, digits, punctuation, symbols, and even most CJK ideographs, which instead serve as components or full ideographs within such sequences. Characters assigned this value lack the specific grammatical role of introducing a standalone, unencoded character by its description, and they cannot appear as the operator that precedes a single radical or stroke set in that context. Thus, No simply indicates the absence of that syntactic function, covering every code point not explicitly designated as an operator.
