Concise term for non-ASCII Unicode characters

[Sean Leonard]

What is the most concise term for characters or code points outside of 
the US-ASCII range (U+0000 - U+007F)? Sometimes I have referred to these 
as "extended characters" or "non-ASCII Unicode" but I do not find those 
terms precise. We are talking about the code points U+0080 - U+10FFFF. I 
suppose that this also refers to code points/scalar values that are not 
formally Unicode characters, such as U+FFFF. Basically, I am looking for 
a concise term for values that would require multiple UTF-8 octets if 
encoded in UTF-8 (without referring to UTF-8 encoding specifically). 
"Non-ASCII" is not precise enough since character sets like Shift-JIS 
are non-ASCII.

Also a citation to a relevant standard (whether Unicode or otherwise) 
would be helpful.

The terms "supplementary character" and "supplementary code point" are 
defined in the Unicode standard, referring to characters or code points 
above U+FFFF. I am looking for something like those, but for characters 
or code points above U+007F.

Thank you,

Sean
