Hi,
I was trying to export a table in a specific oracle database (which is in WE8MSWIN1252 character set) and I'm getting trouble: Following is the steps:

$exp

try to just continue with export WITHOUT setting the NLS_LANG.
As export tool says, most of charactersets are subject to autoconversion.
If you cannot import this into target,
then, we will find someworkaround

Do you have a locally created system table in the schema you are trying to export. (DUAL,USER_TABLES etc?). In that case export would expect records to be present in these the local system tables.

Yes. I just checked it in and it seems ok.
Actually I did test several techniques and very strange. When I run an export with .bat file, it seems to work well...
