al32utf8 is not a binary superset of WE8ISO8859P1; check Metalink Note #260192.1

WE8MSWIN1252 is a binary superset of WE8ISO8859P1. So I need to first convert clob data to WE8MSWIN1252. Metalink Note #260192.1 does suggest the same. If this is right, could you please let me know the steps involved to convert from

WE8ISO8859P1 to WE8MSWIN1252 and then to al32utf8? Should I do fix the Lossy first? I still have to handle dictionary "convertible data" (sys.source$, sys.metastylesheet and sys.external_tab$).

Thanks,
