The Vietnamese diacritic characters involve the application of two distinct
diacritics to a base character -- one an accent mark indicating
pronunciation, the other a tone mark -- so it makes sense for them to be
decomposable. I don't think this can be extended to decomposition of
diacritic marks into subatomic particles.
