I don't understand this. The set of ASCII characters is a proper and
intact subset of the set of Unicode characters. Whether they are "more
important" than other Unicode characters, or whatever Marion was trying
to get at with her remark about the U.S. and her winky comment in
Swedish about sending a courier to me, was not my point.
The confusion over terminology regarding ASCII and Unicode is still
widespread. Perhaps one of the most bizarre examples I've seen was in
the documentation for Intersystems Caché, a database, which said "Valid
characters may be 8-bit ASCII, or ISO Latin-1 Unicode."
In 2009, we ought to regard ASCII as "ISO 10646, constrained to the
Basic Latin range, represented in UTF-8, with control characters
interpreted as per ISO 6429."
