65001 does not appear to be an option...

MSDN is your friend.

MultiByteToWideChar CP_UTF8 - MSDN Search

MSDN - MultiByteToWideChar

http://msdn.microsoft.com/en-us/library/ms776413(VS.85).aspx

above link says UTF-8 supported

Note: For UTF-8, dwFlags must be set to either 0 or MB_ERR_INVALID_CHARS.

Otherwise, the function fails with ERROR_INVALID_FLAGS.

_WinAPI_MultiByteToWideChar returns a struct

from help file:

Return Value

Success: Structure that contains the Unicode character string

#include <WinAPI.au3>
Global Const $CP_UTF8 = 65001

$String = "ChÆ°a Äủ Bá»"
$tS = _WinAPI_MultiByteToWideChar($String, $CP_UTF8) ;$iFlags default is 0

$s = DllStructGetData($tS, 1) ;struct is byte array, *char[n], byte[n] and ubyte[n] return all element data when index is omitted.

MsgBox(0, "", $s & @CRLF & _WinAPI_WideCharToMultiByte(DllStructGetPtr($tS)))
