What encoding is used to open the go language?

The go language is opened with UTF-8 encoding by default. UTF-8 is a universal character encoding that supports almost all character sets and languages ​​in the world. Using UTF-8 encoding can ensure that the go language Good compatibility when processing texts in different languages. In addition to using UTF-8 encoding, the Go language can also handle other encoding formats through third-party libraries, such as GBK, Big5, etc. By importing the corresponding encoding libraries, files in different encoding formats can be read and processed.

Go language is an open source programming language developed by Google and released in 2009. It is designed as a modern language that aims to provide a concise, efficient and reliable way to write code. Unlike many other programming languages, Go language has its own unique characteristics in coding.

First of all, Go language uses UTF-8 encoding format by default. UTF-8 is a universal character encoding that supports almost all character sets and languages ​​in the world. Using UTF-8 encoding ensures that the Go language has good compatibility when processing text in different languages.

In Go language, you can use the following code to specify the encoding format of the source file:

// go语言使用UTF-8编码打开
package main
import (
"golang.org/x/text/encoding/simplifiedchinese"
"io/ioutil"
"os"
)
func main() {
file, err := os.Open("test.txt")
if err != nil {
panic(err)
}
defer file.Close()
reader := simplifiedchinese.GB18030.NewDecoder().Reader(file)
content, err := ioutil.ReadAll(reader)
if err != nil {
panic(err)
}
// 处理文件内容
// ...
}

The above code example demonstrates how to use UTF-8 encoding to open a text file in Go language. In the code, a file named `test.txt` is opened through the `os.Open` function, and the `simplifiedchinese.GB18030.NewDecoder().Reader(file)` part specifies the encoding format used when opening the file. Then, the `ioutil.ReadAll` function reads the file content as a byte stream and stores it in the `content` variable. The file content can then be processed.

In addition to using UTF-8 encoding, the Go language can also handle other encoding formats through third-party libraries, such as GBK, Big5, etc. By importing the corresponding encoding library, files in different encoding formats can be read and processed.

In short, the Go language uses UTF-8 encoding format to open files by default, which has good compatibility when processing text in different languages. At the same time, by using third-party libraries, you can also operate files in different encoding formats. This makes the Go language ideal for processing multilingual text
