MapVirtualKey is implemented as unicode and ansi function. Quote MSDN:
Function Information
Minimum DLL Version user32.dll
Header Declared in Winuser.h, include Windows.h
Import library User32.lib
Minimum operating systems Windows 95, Windows NT 3.1
Unicode Implemented as ANSI and Unicode versions.
Which means: Call MapVirtualKeyA for ansi strings, MapVirutalKeyW for
unicode strings.
