Hi Guru's

I am in China. I am facing NLS_LANG problem. Let me explain you the scenario.

I have created one database and imported data from the existing database. Both are created as their NLS_CHARCTER_SET=UTF8. It is Chinese database. After importing successfully, when I see the data all I am getting just "????????", no Chinese character display. Please help me where I did the wrong?

I observed there is no NLS_LANG environment variable set. Please guide, If it is require what value i need to set. And when to set, before the EXP or just before IMP into newdb.

Here are the NLS parameters for the exported DB and new DB

NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA
NLS_CURRENCY $
NLS_ISO_CURRENCY AMERICA
NLS_NUMERIC_CHARACTERS .,
NLS_CHARACTERSET UTF8
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR
NLS_DATE_LANGUAGE AMERICAN
NLS_SORT BINARY
NLS_TIME_FORMAT HH.MI.SSXFF AM
NLS_TIMESTAMP_FORMAT DD-MON-RR HH.MI.SSXFF AM
NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZH:TZM
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH.MI.SSXFF AM TZH:TZM
NLS_DUAL_CURRENCY $
NLS_COMP BINARY
NLS_NCHAR_CHARACTERSET UTF8
NLS_RDBMS_VERSION 8.1.6.0.0

Please consider this as very urgent and guide me in this regard.
