Cased - No
No is the designation for characters that do not meet the criteria for being considered cased, meaning they lack the distinction between uppercase and lowercase forms. This includes letters from scripts without case, such as Arabic, Hebrew, and Thai, as well as symbols, punctuation, digits, and whitespace. No also applies to characters that are inherently caseless even if they appear in a cased script, like certain modifier letters or phonetic extensions that have no uppercase or lowercase variant. Additionally, characters that are solely numeric, combining marks, or control codes fall under this value. In essence, No covers every code point that cannot be mapped to a corresponding counterpart in the opposite case, nor does it exhibit any case-related behavior in text processing.
