如何使用go在Windows控制台中正确输出字符串？

// Alert: This is Windows-specific,uses undocumented methods,does not
// handle stdout redirection,does not check for errors,etc.
// Use at your own risk.
// Tested with Go 1.0.2-windows-amd64.

package main

import "unicode/utf16"
import "syscall"
import "unsafe"

var modkernel32 = syscall.NewLazyDLL("kernel32.dll")
var procWriteConsoleW = modkernel32.NewProc("WriteConsoleW")

func consolePrintString(strUtf8 string) {
    var strUtf16 []uint16
    var charsWritten *uint32

    strUtf16 = utf16.Encode([]rune(strUtf8))
    if len(strUtf16) < 1 {
        return
    }

    syscall.Syscall6(procWriteConsoleW.Addr(),5,uintptr(syscall.Stdout),uintptr(unsafe.Pointer(&strUtf16[0])),uintptr(len(strUtf16)),uintptr(unsafe.Pointer(charsWritten)),uintptr(0),0)
}

func main() {
    consolePrintString("Hello ?n")
    consolePrintString("éè????ùòèì?n")
}
