[Alain] :
You got a nice illustration of the problem we're trying to solve and that I
am confident we will solve it.
We modified that "Latin 0" proposal Wednesday night before we hold the
SC2/WG3 meeting and SC2 Plenary later on this week and next week. Apart
from the EURO, the French ligatures OE, the upper case Y DIARESEIS, the
missing characters for full support of Finnish in Latin 1 (a language
which, like French, was supposed to be covered fully but which was not)
will be added in this new Latin table intended to replace Latin 1 in 5
years at the latest during parallel transition to UNICODE, of course (and,
importantly, as a standard reference for private codes like EBCDIC code
tables on main frames to allow full platform range character integrity).
Btw the missing Finnish characters are upper case and lower case S CARON
and Z CARON.
The proposal was initially a joint France-Canada proposal. It is now
officially a France-Canada-Finland-Ireland-Denmark proposal. Other
countries' support is very likely as per the atmosphere that reigns in
corridors here.
It remains a table intended for use for Western European languages. There
could have been competition between other languages if we had tried to add
2 other characters and therefore we stopped there. It is limited to
correcting current problems internal to Latin 1, taking the opportunity of
the urgent EURO SYMBOL support for making the change (a problem not to be
underestimated in all its implications, human, economical, technical and
psychological, considered in Europe as important as the YEAR 2000 transition).
