for Netscape 6.x
1. we know we have some bug in NCR and UTF-8 conversion. We are fixing
them now.
2. we know our linux/window/mac text rending code do not take care of
Plane 1 yet. We plan to fix the window version in the near future.
Please contact shanjian@netscape.com if you can help (providing
information where to find a font, how to install, how to test, etc)
