Registered schema lost one byte of Chinese character at certain position

Question

Hello all,
I registered a schema as below. When viewing the registered schema in the Enterprise Manager, I found a byte was lost for the Chinese character at the position of byte 4200 ( or 0x1068 ).
before registration:
22 B2 FA C6 B7 CA FD C1 BF B5 A5 CE BB 22 20 ; "产品数量单位"
after registration:
22 B2 FA C6 B7 FD C1 BF B5 A5 CE 3F 20 ; "产品康ノ?
My database (9.2.0.1 & 9.2.0.3) has the character set of SIMPLIFIED CHINESE_CHINA.ZHS16GBK.

dbms_xmlschema.registerSchema('http://www.antu.com.cn/metaxml.xsd',samplexmldoc,True,True,False,FALSE);
End;
Because we have to generate schemas by program, it's not acceptable to adjust the schema text manually.
What shall I do? Thanks for any help.

Please open a tar with your local support organization...

Please excuse me if I ask some basic questions here, I've no previous experience working with documents containing Chinese Character sets.
I assume that if I look at your post with my Brower character set to simplifiedChinese.GB2312 I will see the schema document posted correctly..
Can you test wether or not this problem occurs if the document is encoded in UTF8 and loaded into an AL32UTf8 database. Also, do you see , rather than GB2312. Also are the characters still missing if you view it from SQL*PLUS...
