I am trying to install a new 19c instance of Oracle database in order to migrate a 12c database there. The 12c database uses a database character set of
WE8ISO8859P1 and a national character set of
AL16UTF16, both configured on installation.
I have found during the 19c installation, however, that there is no option to set the national character set. How can I be sure that this is configured to the correct AL16UTF16?
