如何在 Go 中从编码转换为 UTF8

您可以使用the encoding package，它通过包golang.org/x/text/encoding/charmap支持Windows-1256(在下面的示例中，导入此包并使用charmap.Windows1256代替japanese.ShiftJIS).

下面是一个简短的示例，它将一个日本UTF-8字符串编码为ShiftJIS编码，然后将ShiftJIS字符串解码回UTF-8.不幸的是，它在操场上不起作用，因为操场上没有"x"包.

package main

import (
    "bytes"
    "fmt"
    "io/ioutil"
    "strings"

    "golang.org/x/text/encoding/japanese"
    "golang.org/x/text/transform"
)

func main() {
    // the string we want to transform
    s := "今日は"
    fmt.Println(s)

    // --- Encoding: convert s from UTF-8 to ShiftJIS 
    // declare a bytes.Buffer b and an encoder which will write into this buffer
    var b bytes.Buffer
    wInUTF8 := transform.NewWriter(&b, japanese.ShiftJIS.NewEncoder())
    // encode our string
    wInUTF8.Write([]byte(s))
    wInUTF8.Close()
    // print the encoded bytes
    fmt.Printf("%#v\n", b)
    encS := b.String()
    fmt.Println(encS)

    // --- Decoding: convert encS from ShiftJIS to UTF8
    // declare a decoder which reads from the string we have just encoded
    rInUTF8 := transform.NewReader(strings.NewReader(encS), japanese.ShiftJIS.NewDecoder())
    // decode our string
    decBytes, _ := ioutil.ReadAll(rInUTF8)
    decS := string(decBytes)
    fmt.Println(decS)
}

在日本的StackOverflow网站上有一个更完整的例子.文本是日语，但代码应该不言自明:https://ja.stackoverflow.com/questions/6120
