Table-level restore and locales
For table-level restore, if the table being restored (table on the archive) has a locale code set different from the default locale (en_US.8859-1) the DB_LOCALE environment variable must be set to have the same code set as the locale of the archived table being restored.
No code set conversion is performed during a table-level restore; the locale code set of the database or table being restored must match the locale code set of the database or table that the data is being restored to. In addition, the same DB_LOCALE information is used for all of the tables being restored by using the same table-level restore command schema file.
