How to solve the garbled problem of golang binding

Recently when using golang for coding, I found that there was a problem with garbled characters when binding strings. After some searching and trying, I finally managed to solve the problem. Below I will share how to solve the problem of golang binding garbled characters.

1. Confirm the encoding format

First, we need to confirm the encoding format of the string we use. Common encoding formats include UTF-8, GB2312, GBK, etc. If we only use ASCII characters, no matter which encoding method is used, there will be no garbled characters. But if the string contains non-ASCII characters, garbled characters will appear.

2. Use the correct encoding format

After confirming the encoding format of the string, we need to ensure that the correct encoding format is used during the binding process of golang.

In golang, using UTF-8 encoding is the most common situation. Therefore, when binding a string, we can use the following code:

import "unsafe"

func string2byte(s string) []byte {
    x := (*[2]uintptr)(unsafe.Pointer(&s))
    h := [3]uintptr{x[0], x[1], x[1]}
    return *(*[]byte)(unsafe.Pointer(&h))
}

s := string2byte("你好，世界！")

The above code converts the string into a byte slice. This way, strings can be processed normally during the binding process.

3. Manually specify the encoding format

If golang's default encoding format cannot meet our needs, we can manually specify the encoding format. For example:

import "github.com/golang/text/encoding/simplifiedchinese"

encoding := simplifiedchinese.GB18030.NewEncoder()
output, _, _ := encoding.TransformString("你好，世界！")
fmt.Println(output)

The above code encodes the string into GB18030 format. This way, strings can be processed normally during the binding process.

Summary

The binding garbled problem is often encountered in golang, but we can easily solve this problem by confirming the encoding format, using the correct encoding format or manually specifying the encoding format. .
