Actually, no. The definition of "abstract character" in Unicode 2.0
(page 3-4) is the same as the definition of "character" in ISO 10646.
The term "character", on the other hand, is not defined at all
in the normative parts of the Unicode Standard.
The glossary (page G-2) defines "character" in five different ways,
one of which is as a synonym for "abstract character". The
other definitions are: "the smallest component of written language
that has semantic value"; "a 16-bit unit of textual information";
synonym for "code value"; synonym for "Han ideograph".
There is, as far as I can tell, no single term used in the Unicode
Standard for what you are calling an "abstract character" above.
I would like there to be one, myself.
