因为不能通过&获取一个切片的实际数据的地址：
也就是：
// p1 指向 data1 的第一个元素的地址
var data1 [512]byte
p1 := &data1
// p2指向data2切片结构体的地址
data2 := make([]byte,512)
p2 := &data2无法把这个p2作为参数调用c里的函数。
另外，无法在转换前知晓转换后的字符串有多长。
=-=
go要定义一个编译时不知长度的数组可以这么搞：
//#include <stdlib.h>
import "C"
arr := C.malloc(n)跑路……

我的解决方案：
import "io/ioutil"
import "golang.org/x/net/html/charset"
func convrtToUTF(str string, origEncoding string) string {
strBytes := []byte(str)
byteReader := bytes.NewReader(strBytes)
reader, _ := charset.NewReaderLabel(origEncoding, byteReader)
strBytes, _ = ioutil.ReadAll(reader)
return string(strBytes)
}
