Changes When Titlecased - Yes

Yes is the indicator that a character’s default case conversion, when applied to produce a titlecase form, actually alters its original code point. This means that the character, typically a lowercase letter or a special variant, has a distinct uppercase or titlecase counterpart, such as ‘ß’ becoming ‘Ss’ or ‘dž’ turning into ‘Dž’. The value confirms that a textual transformation is necessary for proper titlecasing, often used in headings or names, and it applies to characters that are not already titlecase or uppercase in their base form. This flag helps software know when a character requires an explicit mapping instead of being left unchanged.
