Just NLS parameters that are correctly set or not.
As we don't know when it was correctly set and when it was not (and I bet you don't know either) we can't know what are the correct data and what are the wrong ones.

To be correct, the client should have its NLS parameter set to the character set it actually uses.

Michel

Thanks for replaying...

actually i know that the database in the source is set to AR8ISO8859P6 and it's using Form6i interface .
we want to develop a new application in .NET Environment so when Exporting these data and use it in .NET the data appears as Garbage Confused because .NET reads data that are in AR8MSWIN1256 .

If NLS parameters are correctly set you don't see in which character set the data are stored.
If your .Net application works with AR8MSWIN1256 character set, then set your NLS_LANG parameter accordingly, Oracle will do the conversion automatically during the transfer of the data from database to client.

i don't think that Oracle will do the conversion automatically i have checked the NLS_LANG parameter in my client which is AR8MSWIN1256 and in the server the NLS_LANG is AR8ISO8859P6
