Unicode in MFC
Updated: July 2010
MFC supports the Unicode standard for encoding wide characters on Windows NT, Windows 2000, and Windows XP platforms. Unicode applications cannot run on Windows 98 platforms.
The Unicode versions of the MFC libraries are described below (where xx is the MFC release version):
Unicode MFC static link library
MFCxxU.lib, .dbg, def, .dll, .map, .pdb, .prf
MFCxxUD.lib, .def, .dll, .map, .pdb
Unicode MFC import library (see notes below for explanation of file extensions)
Unicode MFC import library containing code that must be statically linked in an application or DLL
Import library files have the extension (.lib).
Dynamic-link library files have the extension (.dll).
Module definition (.def) files are text files that contain statements for defining an .exe or .dll.
Map (.map) files are text files that contain information that the linker uses when linking a program.
Library (.lib) files are used in conjunction with the DLL versions of MFC. These files contain code that must be statically linked in the application or DLL.
Program database (.pdb) files contain debugging and project state information.
Debug (.dbg) files contain information (COFF FPO, and CodeView) that the Visual C++ Debugger uses.
