I'm surprised that nobody whose responses I've seen has taken the trouble
to actually go to ANSI to see what "ASCII" means to that
A quick search at http://webstore.ansi.org for the word "ASCII" (without
the quotes, of course) shows the following two hits:
Space data and information transfer
systems - ASCII encoded English
ANSI X3.4-1986 (R1997)
Information Systems – Coded Character
Sets – 7-Bit American National Standard
Code for Information Interchange (7-Bit
X3.4-1986, reaffirmed (most recently) in 1997, is a *7*-bit encoding standard.
The only other standard with "ASCII" in its name is an ISO standard dealing
specifically with encoding English (the language, one assumes, and not the
people) in ASCII form.
ANSI appears to have no knowledge of a standard called "8-bit ASCII".
A search for "8-bit" reveals about 24 standards, all but 2 of which are
from ISO, and most of which are parts of ISO/IEC 8859.

I agree. Among the 24 hits I found when searching for "8-bit" is this one:
Information Processing – 8-Bit Single Byte
Coded Graphic Character Sets – Part 1:
Latin Alphabet No. 1
This makes it clear that ANSI *does* have an official 8-bit character
encoding standard but that it is *not* called "ASCII"; this standard became
an ANSI standard by ANSI's adoption of the ISO standard. This standard is
what many people call "8-bit ASCII", but it is not (in any official sense!)

Apparently (from the ANSI website), that did not happen.
Hope this helps,
