Go中等效的C＃的Encoding.UTF8.GetString [关闭]

Question

Whats the equivalent of C#'s Encoding.UTF8.GetString in Go?

As i already know that Go's default encoding is in UTF8 and string(somebytes) in Go would produce a UTF8 encoded string.

C#:

public static void Main()
{
    byte[] bytes = new byte[] { 144, 197, 217, 192, 204, 249, 181, 42, 92, 252, 243, 87, 170, 243, 169, 80, 175, 112, 192, 239};
    string str = Encoding.UTF8.GetString(bytes);

    Console.WriteLine(str);
 }

Go:

func main() {
bytes := []byte { 144, 197, 217, 192, 204, 249, 181, 42, 92, 252, 243, 87, 170, 243, 169, 80, 175, 112, 192, 239}
str := string(bytes)
fmt.Println(str)
}

C# code produces:

�������*\��W��P�p��

Go code produces:

�������*\��W���P�p��

what I am missing here?

Clearly, whatever way you look at it, your bytes are not valid UTF-8.

For example,

package main

import (
    "fmt"
)

func main() {
    bytes := []byte{144, 197, 217, 192, 204, 249, 181, 42, 92, 252, 243, 87, 170, 243, 169, 80, 175, 112, 192, 239}
    fmt.Println(len(bytes))
    fmt.Printf("%v
", bytes)
    fmt.Printf("% x
", bytes)
    fmt.Printf("%q
", bytes)
    fmt.Printf("%s
", bytes)
}

Output:
