How to solve golang garbled code

With the popularity of golang in China, more and more developers have encountered the problem of garbled Chinese characters in golang. This article mainly solves the problem of garbled Chinese characters in golang.

1. The reason why golang Chinese characters are garbled

In golang, due to encoding problems, Chinese characters are converted into UTF-8 encoding, and one Chinese character in UTF-8 encoding takes up 3 bytes, while most programming languages ​​only occupy 2 bytes. So when we use golang to output Chinese characters, we will find garbled characters. This is because golang does not support UTF-8 encoding by default and requires relevant settings.

2. Methods to solve garbled Chinese characters in golang

1. Add the following code at the beginning of the golang source code file:

// 在文件头部添加一些注释有助于标识源代码的编码方式
// +build !release

package main

import (
    "fmt"
)

func main() {
    fmt.Println("午餐吃什么？")
}

2. Use iconvConvert character encoding

iconv is a commonly used character encoding conversion tool that can easily convert Chinese character encoding in golang into other target encodings. For specific operations, please refer to the following code ：

package main

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

    iconv "github.com/djimenez/iconv-go"
)

func main() {
    content := "中文字符"

    // 建立一个缓冲区
    b := bytes.NewBufferString(content)

    // 初始化一个 iconv 转换器
    cd, err := iconv.NewConverter("utf-8", "gbk")
    if err != nil {
        panic(err)
    }
    defer cd.Close()

    // 转换字符串中的字符编码
    result, err := ioutil.ReadAll(cd.NewReader(b))
    if err != nil {
        panic(err)
    }

    fmt.Println(result)
}

3. Summary

It is not difficult to deal with garbled Chinese characters in golang, as long as you know the principle and adopt the corresponding solution. I hope this article can help golang developers better deal with Chinese character issues.
