I was referring to the problem discussed earlier in this thread, where
Web site developers cannot assume that non-Times/Courier users (e.g.
Japanese) have set their Unicode font properly. The default is
Times/Courier, which don't support Japanese, and the Win32 version
doesn't do font switching.

Netscape 4.X is unlikely to support NCRs properly in documents
transmitted in non-Unicode encodings. The architecture doesn't make it
easy to do this in a way that would maintain the performance (speed) and
keep documents looking good on the screen.
Netscape 4.X could add support for hexadecimal NCRs, but I don't know if
it's worth it.
Netscape 4.X is being maintained by a small group.
The open source version is called Mozilla, and is being developed by
Netscape and AOL engineers and external developers. Netscape will
probably ship its own version with the Netscape brand (name), and it may
be called 5.0. I don't know for sure, since that decision is made by
Mozilla already supports NCRs in non-Unicode documents, and hex NCRs
