Other Lowercase - No
No is a designation for characters that are definitively not classified as lowercase in the context of the “Other Lowercase” category, meaning they lack the distinguishing typographic or case-mapping features that define such letters. This value applies to the vast majority of Unicode code points, including uppercase letters, digits, punctuation, symbols, and control characters, as well as lowercase forms that are already recognized under standard case properties. Importantly, “No” does not imply a character is uppercase or non-letter; it simply signals that the character does not qualify for the special subset of lowercase letters that have no corresponding uppercase equivalent, such as certain modifier letters or phonetic extensions. Thus, “No” serves as the default exclusion marker, ensuring that only true lowercase-only characters receive the affirmative designation, while everything else is clearly marked as outside this narrow set.
