사용 참고 사항

AutoShapeNko, AutoShapeAdlam, AutoShapeHanifiRohingya는 RTL cursive GSUB positional path를 text output에 연결합니다. sfThaiLaoReorder는 SARA AM을 decompose하고 tone mark를 order하며, sfHebrewReorder는 mark placement 전에 canonical combining class 기준으로 niqqud를 order합니다. Javanese, Tai Viet, Meetei Mayek, Khmer, Myanmar flag는 cmap-to-GID mapping 전에 script-specific cluster order를 normalize합니다
