>Why this proposal cannot be taken into account by IETF IDN WG?
Elisabeth,
This entire topic, and all its proposals, have very much been taken into
account by the IDN working group. They have been taken into account at the
cost of many months of delay, although this topic is actually outside the
scope of the working group.
The topic calls for an algorithm that equates portions of different
scripts. This goes beyond the model of equating upper/lower case WITHIN a
script.
In fact, this topic is an open research question with no generally accepted
practise. So even if the topic were within scope the solution would, at
best, be very, very risky.
The risk is exacerbated by the fact that this technical approach does not
scale well. As soon as an approach like the TC/SC proposal is added, then
we must find mappings for many, many other multi-script equivalences. That
effort will probably take years.
