Your idea of an extended ASCII is not new. In fact the International
Standardization Organization (ISO), of which ANSI is a member, has already
adopted an extended ASCII character set. It is known as ISO 8859. The
idea has been to extend ASCII with various characters used in languages
other than English. Almost all non-English languages have special letters
(think, for example, of the French accented letters, the Spanish n with
tilde, etc.). ISO 8859 is actually not one standard but several:
ISO 8859/1 is ASCII extended with the letters used in the
western European languages.
ISO 8859/2 is ASCII extended with the letters used in the
eastern European languages.
ISO 8859/3 is ASCII extended with the letters used in the
languages spoken around the Mediterranean.
ISO 8859/4 is ASCII extended with the letters used in the
nothern European languages.
ISO 8859/5 is ASCII extended with the letters used in the
Cyrillic alphabet (i.e. Russian, Bulgarian, etc.).
ISO 8859/6 is ASCII extended with the Arabic letters.
ISO 8859/7 is ASCII extended with the Greek letters.
ISO 8859/8 is ASCII extended with the Hebrew letters.
The ISO 8859 standard is nice and useful, it is, however, unfortunate to
have 8 standards instead of just one.
Adopting your proposal will be unfortunate for two reasons:
1) It would alienate the USA from the rest of the world. If the USA used
an extended ASCII without the national characters used in French,
German, Spanish, etc., those countries would have to follow a separate
path in the computer industry.
2) It would confuse the ISO 8859 abundance of standards further.

There is a 8-bit character set standard already. ISO 8859 is it.
Most of the X/OPEN member companies are implementing support for the
western European variant (ISO 8859/1) already. See the exchanges on this
in comp.std.internat and comp.std.unix for more details.

I think all of this has already been done in the ISO 8859 standard extension
to ISO 2022. Have you read this. In particular IS 8859/7 handles greek.
