csscan for version 805

Do you guys know if the characterset scanner utility was ever available for databases version 805 for NT. I've gone to technet.oracle.com to try to download the scanner, but the closest thing I find at the download page is verison 806 for Solaris and version 816 for NT.

I need to convert an 805 database (NT) from US7ASCII to WE8ISO8859P1. And I'm following the doc at the metalink and it says to run the scanner to see if any data will be lost. But apparently the scanners are specific to the db version and I don't see one that's available for NT version 805.
