Discuss the causes of Chinese garbled problems in golang

Go language (also called Golang) is a fast, efficient, and concise development language developed by Google and launched in 2009. Golang is very popular because of its support for features such as concurrent programming and automatic memory management, making developers more productive and efficient. However, when using Go language to write Chinese applications, sometimes you encounter the problem of garbled Chinese characters. In this article, we will explore the causes of Chinese garbled problems in golang and possible solutions.

1. Character set problem
   In most cases, the problem of golang Chinese garbled characters is related to the character set (encoding). Go supports multiple character set encodings, such as ASCII, UTF-8, and GBK. Therefore, you must explicitly specify the character set used when writing code. If the character set is not specified correctly or an error occurs when converting between different character sets, it will cause garbled Chinese characters.
2. File Encoding Issue
   When we copy and paste Chinese text from other software or operating systems, the encoding of the copied text may be different from that of our system. For example, if we copy a UTF-8 encoded text into a GBK encoded editor, Chinese characters will be garbled.
3. Operating system setting issues
   When setting options such as language and region in the operating system, it may also affect golang Chinese character encoding. If the locale does not support the character encoding we want, it will cause garbled characters.

How to solve the Chinese garbled problem in golang?

1. Use the correct character set
   Because the Go language supports different character set encodings, we need to set the character set correctly in the code. For example, if we want to support Chinese, we should use UTF-8 encoding. In the Go language, you can use the encoding package in the Go standard package to specify the character set. For example:

import "encoding/json"

data := struct{
Name string `json:"name"`
Age  int    `json:"age"`
}{
Name: "张三",
Age:  20,
}

jsonBytes, _ := json.Marshal(data)
jsonData := string(jsonBytes)
fmt.Println(jsonData)

This code converts structure data into JSON format data and prints it out. In this example, we use the json.Marshal() function to convert the data structure into JSON format data. The character set used by this function when converting is UTF-8.

2. Use consistent file encoding
   When editing a file, we need to ensure that the encoding of the file is consistent with the character set settings in our code. For example, if the character set we set is UTF-8, we should set the file encoding to UTF-8 in our editor. If we copy and paste Chinese text in the operating system, we need to ensure that the copied text is converted correctly into the character set we are using.
3. Check operating system settings
   We need to ensure that the language and regional settings in the operating system are consistent with the character set we are using. For example, if we use UTF-8 encoding, we should set the language and region in the operating system to UTF-8.

Summary

The Chinese garbled problem in golang is usually not a problem with the Go language itself, but is caused by factors such as character set, file encoding, and operating system settings. To avoid these problems, we need to ensure that the character set is set correctly in the code, use consistent file encoding, and check the operating system settings. As long as we follow these best practices, we can avoid encountering golang Chinese garbled problems and make our code more standardized and effective.
