I'm puzzled at your repeated reference of '8bit system'. I'm not sure
what you exactly meant by that. Neither am I sure I have to answer your
question on this list(as opposed to sending a reply to you only) because
you seem to be asking too obvious a question nobody on the list to care
to answer. MacOS has been able to handle multibyte encodings(i.e. 8bit
AND 16bit) for CJK since 7.0(with WS I and WS II extensions bundled in
Mac OS 7.5 or later by default, all you need to view CJK web pages are
some free fonts. i.e. Language Kit is not necessary for just viewing web
pages) and there's absolutely no reason (as far as I know) it can't
handle UTF-8 as well although I don't know whether or not current
version of NS 4.x for MacOS supports that.

Hmm, I can't help getting the impression that you've been away from
the planet for a long time while all these things have been happening
(have you been off this list for a while?) :-). Under both Unix/X11 and
MS-Windows, UTF-8/UTF-7 support of NS 4.0x or later work pretty well(not
just 256 at a time but for the full UCS-2) as far as glyphs are
available. In MS-Windows, you need to have Unicode fonts(one of which is
freely available Cyberbit from Bitstream with over 20k glyphs including
those for Chinese ideograms and quite many Korean Hanguls) to view
UTF-8/UTF-7 encoded pages while in Unix/X11 NS manages to collect glyphs
from fonts available on the system to form a 'Pseudo-Unicode' fonts. As
you wrote, you wrote how to convert to UTF-8 from UCS-2, why don't you
make a script/program to generate a UTF-8 encoded page (with all the
characters in UCS-2) and see how it's rendered by NS 4.x for MS-Windows
and Unix/X11. Also, there are pretty many pages around the net encoded
in UTF-8 these days.
