How is an applet suppose to pass double-byte characters (like chinese GB)
to a text value in an HTML form? JavaScript is used to call a method in
the Java applet.

Do we use Unicode or just GB?

The applet works fine when Netscape 4 is in the ISO-8859 mode; it pass GB
characters in 8-bits byte form back to the HTML form.

But once Netscape switch to GB2312 viewing mode when the applet runs, the
applet seems to pass garbage ???? back to the HTML form. Do we simply just
work with 16-bit Java character value? It doesn't seems to work that way

Do we pass 8bit bytes or 16bit Java char? and in what charset?
