Case Ignorable - No
No is the designation for characters that are not case ignorable, meaning they do affect case folding, casing, or case matching operations. These characters, which include most letters, digits, punctuation, and symbols, are considered when determining case-insensitive comparisons, such as those used in sorting, searching, or matching strings. Unlike their counterparts marked "Yes," they cannot be skipped or disregarded during such processes; each occurrence must be accounted for. This value applies to the vast majority of code points, including all basic Latin letters (both uppercase and lowercase), all decimal digits, and common punctuation like periods and commas. The distinction is crucial for algorithms that need predictable and consistent behavior, ensuring that only specific characters, like combining marks or certain modifiers, are ignored while all others are treated as significant.
