如何在Go中从编码转换为UTF-8? [英] How to convert from an encoding to UTF-8 in Go?
问题描述
我正在一个项目中,我需要将文本从编码(例如Windows-1256阿拉伯语)转换为UTF-8.
I'm working on a project where I need to convert text from an encoding (for example Windows-1256 Arabic) to UTF-8.
我该如何在Go中执行此操作?

推荐答案
您可以使用编码包,其中包括通过包 golang.org/x/text/encoding/charmap
对Windows-1256的支持(在下面的示例中,导入此包并使用 charmap.Windows1256
而不是 japanese.ShiftJIS
).
You can use the encoding package, which includes support for Windows-1256 via the package golang.org/x/text/encoding/charmap
(in the example below, import this package and use charmap.Windows1256
instead of japanese.ShiftJIS
).
这是一个简短的示例,该示例将日语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"包装.
Here's a short example which encodes a japanese UTF-8 string to ShiftJIS encoding and then decodes the ShiftJIS string back to UTF-8. Unfortunately it doesn't work on the playground since the playground doesn't have the "x" packages.
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)
}
日语StackOverflow网站上有一个更完整的示例.文字为日语,但代码应不言自明: https://ja.stackoverflow.com/questions/6120
There's a more complete example on the Japanese StackOverflow site. The text is Japanese, but the code should be self-explanatory: https://ja.stackoverflow.com/questions/6120
