Hello there,

I have an Oracle DB's charset configured for Korean language and things in there are English and KOrean and they are working fine.

If i try to import a txt file with Chinese chararcters into the DB. It doesnt show correctly on query.

Is there any way I can solve this ? Since I find that there are many charset / NLS language options througout DB.

I read from others that they have the following response. Any alternative beside changing the whoel DB charset ?

thanks
Clement

Recreate the database with the correct character set
Convert the database to AL32UTF8. Documentation link
Change the databases National Character Set to AL32UTF8 & change your application to use NVARCHAR2()/NCHAR() datatypes instead of VARCHAR2() (documented at the same link as above)

Only proper way to establish database character set is at DB creation.

If you simply display (TYPE textfile.txt) the file that contains the Chinese characters, are they properly displayed?

Expected behaviour.

Recreate the database with AL32UTF8 character set.
