Oracle DataPump Exports in Different Charset
I am getting the following warning on Datapump export from my Oracle database:

    Export done in WE8ISO8859P1 character set and UTF8 NCHAR character set
    server uses UTF8 character set (possible charset conversion)

This is causing (I believe) the following export warning:

    EXP-00091: Exporting questionable statistics.

My `$NLS_LANG` environment variable is set to `AMERICAN_AMERICA.UTF8`. The database is in `UTF8` for everything (local and national).

How can I fix this? Thanks.
