Concise term for non-ASCII Unicode characters

[Peter Constable]

Well, if the point is to refer to characters that would require two or more code units in UTF-8, then _accurate_ expressions would be, "Unicode characters beyond the Basic Latin block" or "Unicode characters above U+007F".

Exactly. I think the reason that non-ASCII feels non-concise is that there is widespread confusion between ASCII and Latin-1/ISO 8859-1 (which in turn is widely confused with Windows-1252).
