Unicode Topics

HomeOverviewHow Do ISample

On Windows NT platforms, MFC supports the Unicode standard for encoding wide characters. Unicode is not presently supported on Windows 95.

Note   The Unicode versions of the MFC libraries are not copied to your hard drive unless you select them during a Custom installation. They are not copied during other types of installation. If you attempt to build or run an MFC Unicode application without the MFC Unicode files, you may get errors.

To copy the files to your hard drive, rerun Setup, choose Custom installation, clear all other components except "Microsoft Foundation Class Libraries," click the Details button, and select both "Static Library for Unicode" and "Shared Library for Unicode."

The Unicode versions of the MFC libraries are described below:
