Character Shape Feature Type

The character shape feature type (kCharacterShapeType) is used when a single font contains different appearances for the same character shape, and these shapes are not traditionally treated as swashes. It is needed for languages such as Chinese that have both traditional and simplified character sets, as shown in Figure B-4. In fact, Chinese usually has several alternatives for traditional characters sets.
