Following up today's discussion:
* There is no universally accepted definition of diacritics we could
use, in Unicode or elsewhere. (The original, linguistic definition is
language-specific and thus useless for DNS.) Therefore we are forced
to define it for ourselves.
* The anonymous Unicode expert's argument that "LATIN WITH..." might
include letters that aren't diacritic is, in this context, circular:
if we include them in our defintion then they are diacritics by (our)
definition!
We should choose a definition that works for us. Well-defined,
mechanically testable, predictable, easy to implement &c.
What doesn't matter is whether or not all characters there are
diacritics by some other definition, as long as they don't cause any
problems for our purposes.
