Usage notes

AutoShapeNko, AutoShapeAdlam и AutoShapeHanifiRohingya свързват RTL cursive GSUB positional пътища към text output. sfThaiLaoReorder разделя SARA AM и подрежда tone marks, sfHebrewReorder сортира niqqud по canonical combining class преди mark placement, а флаговете Javanese, Tai Viet, Meetei Mayek, Khmer и Myanmar нормализират скрипт-специфичен ред на клъстери преди cmap-to-GID mapping
