INFO: UNICODE and _UNICODE Needed to Compile for Unicode

ID: Q99359

The information in this article applies to:

Microsoft Win32 Software Development Kit (SDK), used with:
- Microsoft Windows NT versions 3.1, 3.5, 3.51, 4.0
- Microsoft Windows 2000

SUMMARY

To compile code for Unicode, you need to #define UNICODE for the Win32 header files and #define _UNICODE for the C Run-time header files. These #defines must appear before the following:


   #include <windows.h>

and any included C Run-time headers. The leading underscore indicates deviance from the ANSI C standard. Because the Windows header files are not part of this standard, it is allowable to use UNICODE without the leading underscore.
