Yes, two entirely different questions. Question 2 is easy: Not any
time soon, unless you reckon all ASCII data as UTF-8. However, if you
ask, when will multiscript data be mostly in Unicode, I think the
answer is, about another decade. Or if you ask, when will *new*
multiscript data be created in Unicode, that will be rather sooner.
If that sounds too long, remember that the question about getting
past ASCII was raised by Xerox and IBM in 1981 for the U.S. market,
and again by the Macintosh in 1984, and that most Usenet postings and
HTML source files from the U.S. are still in ASCII, and most of the
rest in Windows code pages.

I made similar predictions in a published study in 1994. I think we
were not too dreadfully far off. A few products using Unicode
internally and capable of reading and writing files in one or more
Unicode formats were emerging in 1995. Windows 2000 and Office 2000
support 11 script systems,
fairly reasonably at the Unicode 2.0 level.
(Aside: I am particularly pleased that Access handles CJK data
decently (not perfectly, of course), and I have plans to try it in a
few other scripts. I have imported CJKXREF and much of Unihan into
Access, with added fields for characters, and for Cangjie data.
Pronunciations written in native scripts (Zhuyin, Hangeul, Kana) will
be next, when I get time to write some conversion routines.
Performance in Access is far better for sorts and lookups than Word
tables (shudder) or Excel, and of course Access has queries besides.)
If a high level of Unicode support means rendering for all two dozen
scripts in Unicode 2.0, then obviously we haven't arrived. I believe
that the main remaining technical obstacle for Windows is good
support for complex shaping in several more Indic scripts, Tibetan,
Mac OS X supports even more scripts than Windows 2000, as I
understand it, although I haven't seen any specifics about commercial
application support. Presumably we can get details after the release
Decent Unicode 3.1 support for considerably more scripts should be
available in 2002. The ones with shaping issues are Mongolian,
Syriac, Myanmar, Sinhala, Khmer, and to a lesser extent Ethiopic.
