My code was written in UTF8 and we are unable to display the data in the plsql developer. It can only display all the unreadable character. Please help if anyone have the idea how to do it. Thanks
PL/SQL Developer 7.0.2 and earlier require an explicit national character set on the client. Version 7.0.3, which is in beta now, will be able to access UTF8 (and UTF16) data in the SQL Window and Test Window.
