This page mostly concerns the platforms.h header.

Its main purpose in is to let you easily identify which compiler, OS and ISA is being targeted to potentially implement platform-specific code.

Unicode detection

If UNICODE or _UNICODE are defined, the non-suffixed text-related will have the macro pointing to their unicode variant as is expected on Windows platforms.
