Changes When Casemapped - Yes
Yes is a signal that a character’s code point alters in appearance or form when case mapping operations are applied, meaning it has distinct uppercase, lowercase, or titlecase counterparts. This includes letters that change shape, such as ‘A’ to ‘a’, as well as more complex transformations where a single character expands into multiple characters, like the German ß becoming “SS”, or where context affects the result, such as Greek sigma’s final form. Characters marked this way are not static under case conversion, so software performing case folding or case-insensitive comparisons must treat them as dynamic, not fixed, entries. This value does not indicate the presence of a simple one-to-one mapping; it simply confirms that some casing operation will modify the character, regardless of whether the change is reversible or language-specific.
