Does "dynamic composition" and "equivalent sequences" (2.0, p.2-9)
include composition of combining characters from their parts? Some
Is U+0306 (brev) followed by U+0307 (dot above) the same as U+0310
Is U+0301 (acute) twice the same as U+030B (double acute)?
Is U+307 (dot above) twice the same as U+308 (diaresis)?
Examples 2 and 3 would need careful lateral placement to avoid
unwanted overlap. The "from the center out" rule would solve the
order of codes in the first example and it doesn't matter in the other
If this has been decided and recorded could someone point me to it?
If it has not should it be? I view all three examples as undesirable, but
at the same time I must admit that I favor decomposition of multiple
combining characters for Vietnamese (U+1EA4 and following).
