Could anyone point me in the direction of any guides which could
advise on the likely steps required to make applications code work on
a database created as UTF8 character set versus WE8ISO8859P1 (against
which the application was developed and runs in production now)? I am
really looking for suggested settings of any NLS parameters that might
enable compatibility and a checklist of the things that might need to
be reviewed.

Appreciate any pointers

many thanks
