As to standards, UTS#18 'Unicode Regular Expression' Requirement RL1.2
requires the support of the 'property' it calls 'ASCII', which is
defined in Section 1.2.1 as the property of being in the range U+0000 to
U+007F. This implicitly makes 'not ASCII' a derived property held by all
the other codepoints. If you fear that your audience will think that
Latin-1 characters are ASCII, you'll just have to go for the clumsy
'not 7-bit ASCII'  and accept that there isn't an unambiguous way in
English of turning that into an adjective or noun.

If a term were invented, you'd generally have to explain it, and you
would do better just to remind readers what ASCII is.
