There are plenty of MBCS based legacy MFC applications out there that require CJK language support. Migrating to Unicode is not an option in these cases.
All the resources such as menus, dialogs, string tables used by the application are defined in the .rc file.
However this rc file will not be a part of the application. It will be part of separate resource only DLL known as satellite Dll, There will be one satellite Dll for each language supported by the application. The main application just loads the satellite dlls for the current code page and avails the resources such as menus, dialogs, string tables.
Steps for setting language
1. For MBCS applications, the correct code page i.e, Japanese, chinese traditional or simplified, should be first set in the control panel.as shown below. The system should be restarted.
2.The .RC file must be encoded in the correct format as shown in the table below:
Japanese ShiftJIS
Chinese Traditional Big5
Chinese Simplified GB312
3. Language specific changes should be made in the RC file. An example for Japanese is shown below.
4. Use Unicode Win32 APIs for rendering.
Sometimes some special characters such as subscript and superscript are not rendered correctly as they are not available in the codepage. In such cases Unicode Win32 apis can be used in the subclassed controls such as radio buttons.
