Viewing the Japanese characters in the database
How It Works
East-Asian languages use the double-byte format. To support double-byte data, the fields in the
database table must be defined using the N-prefixed data types. For instance, you must use
NVARCHAR2 instead of VARCHAR2, and NCHAR instead of CHAR.
For other languages such as Spanish, German, or Italian (which are single-byte character
languages), you will not need to use the N-prefixed data types. This will help save space in your database
because, as you can probably guess, N-prefixed data types take up double the amount of space in the
database.

Problem
Depending on the browser language preference setting, you need your application to display the user
interface (all labels, messages, names, and field captions) in the corresponding preferred language of the
application user.
