And in ISQL you can always see that by saying:

SQL> show database;
Database: eins
Owner: SYSDBA
PAGE_SIZE 4096
...
Default Character set: NONE

So this database has been created with no default character set. Which
means that failing to specify a CHARACTER SET for a character column
will mean random bytes may get in, which is typically not desirable.
