This array represents a sequence of nested bidirectional embeddings or overrides, in order from outermost to innermost, with (kCTWritingDirectionLeftToRight | kCTWritingDirectionEmbedding) corresponding to a LRE/PDF pair in plain text or in HTML, (kCTWritingDirectionRightToLeft | kCTWritingDirectionEmbedding) corresponding to a RLE/PDF pair in plain text or a in HTML, (kCTWritingDirectionLeftToRight | kCTWritingDirectionOverride) corresponding to a LRO/PDF pair in plain text or </bdo
