I'm exporting an 8.0.5 database into an 8.1.6 database. The 8.0.5 database is using the WE8ISO8859P1 character set, while 8.1.6 is using US7ASCII.

When I tried to import it, I got

IMP-00038 Could not convert to environment character set's handle
Cause: This is an internal error.
Action: Contact Oracle Customer Support

I'm in the process of opening a tar (Metalink is SLOW today)

I'm wondering if it's something I can just fix myself. Maybe set my environment NLS_LANG to US7ASCII and export the 8.0.5 again, and maybe export will do the converion.

Any other ideas I can try while I wait for support to get back to me?
