How to perform encoding conversion in golang

The method for encoding conversion in golang is: 1. Create a Go sample file; 2. Import the "encoding" and "unicode/utf8" packages in the standard library; 3. Define a function "utf8ToGBK" to accept A UTF-8 encoded string is taken as input and a GBK encoded string is returned; 4. Call the "utf8ToGBK" function and print the result.

Operating system for this tutorial: Windows 10 system, Go1.20.1 version, Dell G3 computer.

For encoding conversion in Golang, you can use the `encoding` and `unicode/utf8` packages in the standard library.

The following is a simple sample code to convert UTF-8 encoded string to GBK encoding.

1. First, you need to import the following package:

import (
    "fmt"
    "golang.org/x/text/encoding/simplifiedchinese"
    "golang.org/x/text/transform"
)

Next, we define a function `utf8ToGBK`, which accepts a UTF-8 encoded string as input and returns a GBK encoding String.

func utf8ToGBK(input string) (string, error) {
    // 将输入的UTF-8编码的字符串转换为字节数组
    inputBytes := []byte(input)
    // 定义一个transformer，将UTF-8编码转换为GBK编码
    transformer := simplifiedchinese.GBK.NewEncoder()
    // 执行转换
    outputBytes, err := transform.Bytes(transformer, inputBytes)
    if err != nil {
        return "", fmt.Errorf("convert to GBK failed: %v", err)
    }
    // 将转换后的字节数组转换回字符串
    output := string(outputBytes)
    return output, nil
}

Finally, we call the `utf8ToGBK` function and print the output result:

func main() {
    input := "你好，世界！"
    output, err := utf8ToGBK(input)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(output)
}

Run this program, the output result should be:

Note that this string is GBK Encoded, garbled characters may appear on some monitors due to the inability to correctly parse GBK.
