Implementing Chinese language in Oracle 11g

Question

Hi,
I had implemented Chinese language (along with the default English) in oracle 8i (Version 8.1.7) database with Character set = UTF8 and NLS_LANG=AMERICAN_AMERICA.UTF8.I am able to insert chinese as well as English characters through Forms 6i(Client side) into the above 8i database(server side).
I created Oracle 11g(Release 1) database with following configurations :
character set=AL32UTF8
NLS_LANG=AMERICAN_AMERICA.AL32UTF8 (in Registry)
But, when i try to  insert the Chinese characters, Then i can see only the symbol '??????????' gets reflected from the database.
ALTER SESSION SET NLS_LANGUAGE="SIMPLIFIED CHINESE" NLS_TERRITORY=CHINA;
Also i tried the above command, but I end up only with ??????? instead of Chinese characters in SQL prompt.
Kindly provide the configurations needed to be made(both in the Client & Server side) to implement Chinese language (along with the default English) in Oracle 11g(Release 1) database.
With Regards,
Abul and srini

Following Metalink documents speaks about 11g(UTF8) Database with Forms 6i compatibility.
{font:helvetica}*Doc_ID : 260893.1*{font} - Speaks about {font:courier}UTF8 With S{font}{font:helvetica}{font}{font:courier}upports 8.0-11g Verssions{font}
{font:helvetica}*Doc_ID :* {font}{font:helvetica}*237593.1*{font} - Speaks about converting 11g DB AL32UTF8 to UTF8 for Oracle 8.0 support
As per the documents i have applied 11.1.0.7.0, and using CSALTER converted my db to UTF8.
Now i am able to connect forms6i with UTF8 11G Database. But Chenese charactors not getting saved.
In OS level i have set following environments.
Installed Chinese Language in Database and form 6i servers.
Changed registry NLS_LANG=AMERICAN_AMERICA.UTF8 in both Database and Forms Servers Home.
Please help.
