Other Lowercase - Yes
Yes is the designation for a character that is classified as lowercase but is not part of the standard cased alphabets typically handled by case mapping. This includes characters like phonetic letters, modifier letters, or special script symbols that inherently have a lowercase form yet lack a corresponding uppercase counterpart or do not undergo simple case conversion. Such characters are often used in linguistic notation, orthographies with unique alphabets, or technical transcriptions, and they are treated as lowercase for algorithmic purposes like sorting or pattern matching, even though their shape or use differs from conventional letters like a, b, or c. The value indicates that the character’s lowercase status is recognized, but it does not imply it can be uppercased in a typical way.
