I export a user table from Oracle 10g in windows.
The I tried to import it in Oracle 10g in Centos 5
But I could not see the language is used(BENGALI).
IT shows me (?????????)

During export my parameter settings where ,

NLS_NCHAR_CHARACTERSET='AL16UTF16'
NLS_CHARTERSET='UTF8'

I also kept same settings in Linux.

import done in US7ASCII character set and AL16UTF16 NCHAR character set
import server uses UTF8 character set (possible charset conversion)
export client uses UTF8 character set (possible charset conversion

But I no result..

Can any one help me with this issue

Thanks in advance ..

Correctly set your NLS_LANG environment parameter.

Where should I set the NLS_LANG parameter in Centos environment variable ??

or In Linux database to which I made import.

or in xampp webserver

Can you explain How NLS_Parameters work during export or import.

I am not good in oracle

In the client session that exports AND in the one that imports.

NLS_LANG tells Oracle which characters set your client is using or supporting (among other things). Oracle translate from the character set of your database to your client character set during import (and the opposite during export).
So if your set a NLS_LANG with a character set that does not support Bengali character (like US7ASCII) they are translated to a "replacement character" (which seems to be '?' in your case).

At previous server

First I set NLS_LANG=AMERICAN_AMERICA.UTF8 in XP by regedit
then I export it.

At new Server
I set my environment variable in Centos 5
NLS_LANG=AMERICAN_AMERICA.UTF8
then import it.

At centos it shows me

Export file created by EXPORT:V10.02.01 via conventional path
import done in UTF8 character set and AL16UTF16 NCHAR character set
import server uses AL32UTF8 character set (possible charset conversion)

But I am seeing the same ??? mark in my webclient.

I also tried the above procedure using
NLS_LANG=AMERICAN_AMERICA.AL32UTF8

But result is same.

I cannot find where the problem is ??
