2. Use NeiMa input method to enter following characters in the chatroom:
CJK entention A character in code range u+3400--u+4DBF 
minority characters in 
Mongolian Characters: U+1800 -- U+18A9
Tibetan Characters: U+0F00 -- U+0FCF

These characters are displayed as question marks. one charcter will be displayed
as one question mark.
3. If copy/paster these characters from navigator window to java applet, one
character will be displayed as two question marks.

Notes：
1. on Java Applet, GB2312 and GBK characters don't have this display problem.
2. In <J2re1.4.0_01>\lib folder, font.properties.gb18030 does exist.

I think this is a duplicate of Java Applet CJK input bug.  
Java Applet is having problem not only with Extension A chars; but all CJK.
(I dont' remember which)

Yes, the other bug is bug 155670, basically java applet need improve i18n support.

Same problem on yahoo-China chat room page: http://cn.chat.yahoo.com

It's a java bug for me too.  cc some sun people.

But it seems not a dup of bug 155670 for me though.  The difference between this
one and bug 155670 is:
this bug is for a pure extension A characters support, it happens on WinXP-SC
with gb18030 fonts installed.  The other one is for non-native OS.

I think it's dup; but we should get a second opinion from sun people.

[Xiaobin Lu]

I guess it it a dup of 155670. Can someone verify this?

Comment 8

[ji]

Xiaobin, this is NOT a dup of bug 155670.
The problem reported in this bug is that Java Applet can't display CJK extension
A chars even on a NATIVE Simplified Chinese system while bug 155670 is about
Chinese display on a non-Chinese system.

Comment 9

Basically Java needs to improve its support for CJK Extension A characters on a
NATIVE system.

Mass-closing bugs in the "OJI" component: OJI plugin integration was replaced with npruntime long ago, and these bugs appear to be irrelevant now. If there is in fact a real bug that remains, please file it new in the "Core" product, component "Plug-ins".
