Doesn't it create a new equivalence for the sequences <ij, diaeresis> and <ij> if neither of them are followed by another combining above diacritic ? If we dont want such equivalences, the Unicode standard should say then that it's illegal to use two consecutive identical combining diacritics. Or simply forbid using <ij,diaeresis> alone (not followed by another diacritic with CC=230). Yes this is really tricky, and academic, I admit. But what forbids encoding two superposed arrows above any letter? Or encoding a <ij,macron> (with the dots removed from ij) followed by diaeresis, which could have a mathematical meaning? -- Philippe.
