Unless you want to interchange the data reliably. ISO/IEC 10646 is
intended to support data interchange. PHAISTOS SIGN TATTOOED HEAD is
what it is, and all sorts of materials may cite it.

We have lots of characters which don't meet your notion of plaintext, then.

Nonsense. This is not a dismissal of the character-glyph model. But
that model is just that -- a model. It guides us. It does not bind
us. Otherwise all sorts of legacy cruft would not have been allowed
to be encoded. And that cruft is still being added to the standard,
in big great buckets. We don't complain because the Chinese are rich
and powerful, and because we recognize that the interchange of their
lexicographical corpus is something worth supporting.

No, but neither is it irrelevant to European culture and literature.

Not at all. A precomposed letter with diacritical marks is disallowed
because it can already be represented by a string of characters.
Phaistos characters cannot be represented by a base letter and a

I think this shows that you haven't really looked at the Phaistos
disk corpus. Small as it is, I think it's pretty clear that none of
those characters is a glyph variant of any other one. You're playing
devil's advocate, I suppose.
