I am inserting Japanese characters into the DB using SQL Plus, when i query the table i am surprise to see some junk characters. But when i insert the same with the front end application, data in the DB is fine. I tried inserting Chinese characters in the same way, i mean using sql plus and didn't find any junk values in the DB. DB is UTF8. Japanese characters encoding type is "Shift JIS". Can any one suggest me regarding whether any settings (DB/Server) to be changed to support Japanes characters.....Could any one tell me which oracle versions support inserting Japanese characters.
