Yes, for sure. But I don't expect to have a fully Unicode-aware operating
system, including Unicode text files and Unicode editors, before about the
year 2003. Some applications will come earlier (currently I have at least
partially Unicode aware web browsers and news readers at my hand). However,
due to the universal scope of Unicode (think of identifiers in programming
languages) there will be a longer time of overlap between old technology
and the new technology to come.

I see *all* proposed UTF schemes as migration schemes which help a smooth
upgrade untill the fully Unicode aware operating systems are on everybodies'

The VT terminal protocol uses the C1 character set. It will cause several
terminal actions there. The VT terminals allow display of e. g. Latin-1.
