Now that <I><dot-above> is downcased to <i> as an exceptional case, Then, we have an interesting question: which direction should we lowercase <I><dot-above><acute> into ?
1. <I dot-above><acute> ===> <i><acute> : CaseMap(NFKC(x)) 2. <i><dot-above><acute> : NFKC(CaseMap(x)) Does the whole combining sequence inherit the bicameral property of the base character or the partial combining sequence minus the last mark ?
