[ansi-test-devel] both-case-p and Unicode titlecase?

[Raymond Toy]

What do other implementations do with characters like
Greek_Capital_Letter_Omega_With_Prosgegrammeni?

In cmucl, this character is both-case-p, but is not lower-case-p and is
not upper-case-p.  Instead, it is title-case-p.  char-downcase returns
#\Greek_Small_Letter_Omega_With_Ypogegrammeni.

Issues like this cause cmucl to fail both-case-p.2 test.
