In addition to Doug's historical clarification, you need to
understand this as a perfectly normal linguistic process of
attributive disambiguation of a term which had grown ambiguous
Many, many people using computers, including some software engineers,
don't even know what the acronym ASCII stands for, or that
the "A" was derived from "American" originally.
ASCII proliferated into parlance meaning basically the default
7- or 8-bit character set of personal computers (<== note that
that term itself is now archaic and disappearing), and in particular the
common set of characters printed on most keycaps. In some
contexts, ASCII meant and still means "not EBCDIC".
"US-ASCII" was invented as a term, I believe, in part to tie
usage back explicitly to ANSI X 3.4, whose repertoire is
identical to U+0000..U+007F, including the implied usage of
a particular set of ISO 6429 controls for C0 ... and opposed
to ISO 646 IRV, or any particular national variant of ISO 646,
including even the US variant of ISO 646, or Code Page 437, or
some other unspecified "ASCII" code page.
