How to solve golang println garbled code

Golang is widely loved by developers as a fast and efficient programming language. However, sometimes we encounter strange problems, such as golang's println function outputting garbled characters. This problem is generally caused by inconsistent character encoding.

Strings in Golang are encoded in UTF-8, and the println function uses standard output by default, which is the console. In the console, the system default character encoding is generally used. In Windows systems, the default character encoding is GBK or GB2312, which is inconsistent with UTF-8 encoding. Therefore, when the string is output in the console, garbled characters may appear.

The solution to this problem is to set the console's character encoding to UTF-8. In Windows systems, we can follow the following steps to set up:

1. Open the command prompt

In Windows systems, you can use the Win R shortcut key to open the run window, Type "cmd" and press Enter to open the command prompt.

2. Set character encoding

In the command prompt, we can use the chcp command to set the character encoding. Enter chcp 65001 and press Enter to set the character encoding to UTF-8. As shown below:

C:\> chcp 65001

3. Run the Golang program

After setting the character encoding, we can normally output the UTF-8 encoded string in the console. In Golang, we can use the Println function in the fmt package to output a string. In the code, we need to specify the character encoding of the output stream as UTF-8 to ensure correct output. The code example is as follows:

package main

import (
    "fmt"
    "os"
)

func main() {
    f, err := os.OpenFile("log.txt", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
    if err != nil {
        fmt.Println(err)
        return
    }
    defer f.Close()
    fmt.Fprintf(f, "Hello, 世界")
}

4. Compile and run the program

After writing the program, we need to use the go build command to compile the program and run the generated executable file. In the console, enter the following command to compile:

C:\go\src\helloworld> go build

After the compilation is completed, we can run the program. In the console, enter the following command to run the executable file:

C:\go\src\helloworld> helloworld.exe

When running the program, we will find that "Hello, world" has been output normally in the log.txt file.

Summary

In Golang, if we encounter the problem of garbled console output, we can solve it by setting the character encoding. On Windows systems, you can use the chcp command to set the character encoding to UTF-8. In the program, we need to specify the character encoding of the output stream as UTF-8 to ensure correct output. In this way, we can easily solve the problem of garbled output by the golang println function and improve the readability and maintainability of the program.
