Annotation Feature Type

The annotation feature type (kAnnotationType) specifies annotations (or adornments) to basic letter shapes. For instance, most Japanese fonts include versions of numbers that are circled, are enclosed by parentheses, have periods after them, and so on. Figure B-1 shows some glyphs that are drawn with annotations.
