The term "code point" existed long before Unicode did. In the context of
Unicode, the term is used as if it is unique to Unicode, but it definitely
is not.

Look at:
http://support.sas.com/documentation/periodicals/obs/nls_article.html ("SAS
System Support for International Character Sets"), which is from the SAS web
site. SAS is software that has existed a long time. Under "EBCDIC" it says
"the rest of the code points". It is talking about EBCDIC, which is the IBM
charcter set that extended ASCII long before Unicoder; I think EBCDIC was
created about 1964. I could find similar comments in the IBM web site, but I
hope the SAS page is enough.

In IBM's AIX documentation is the "Printer Code Page Translation Tables"
page; see:
http://publib.boulder.ibm.com/infocenter/pseries/index.jsp?topic=/com.ibm.aix.doc/aixbman/printrgd/prt_code_page.htm
It talks about code points, but not Unicode code points.
