How to solve garbled characters in golang

Golang is a programming language with excellent development efficiency and performance. However, when using Golang to write applications, we may encounter the problem of garbled characters.

Character garbled characters refer to problems that occur when converting text between different encoding methods. If we convert a text encoded in UTF-8 format to GBK format, some of the characters may be lost or converted to other characters, resulting in garbled characters.

So how to avoid the problem of garbled characters in Golang? Here are some solutions:

1. Use UTF-8 encoding

Golang uses UTF-8 encoding by default, so when writing Golang programs, we should use it as much as possible UTF-8 encoding. If we need to read and write files or network data, we should use Go's built-in UTF-8 support library.

2. Clearly specify the encoding method

When reading or writing files and network data, we can use the related functions provided in the bufio and io package and specify Specify the encoding method to avoid garbled characters.

For example, when reading a file encoded in GBK, we can use the following code:

f, err := os.Open("file.txt")
if err != nil {
    log.Fatal(err)
}
defer f.Close()

r := bufio.NewReader(f)
decoder := mahonia.NewDecoder("gbk")
for {
    line, err := r.ReadString('\n')
    if err != nil {
        if err == io.EOF {
            break
        }
        log.Fatal(err)
    }
    line = decoder.ConvertString(line)
    // ...
}

Here we use the third-party library mahonia to convert GBK encoding to UTF-8 encoding .

3. Uniform encoding method

If our program needs to process data in multiple encoding methods, then we should convert them all into the same encoding method and use it in the program This encoding method is used uniformly in .

For example, when reading a set of data, we can use the following code:

data := []byte{0xaa, 0xb0, 0xbd, 0x35, 0x35, 0x38, 0x35}
decoder := simplifiedchinese.GBK.NewDecoder()
utf8Data, err := ioutil.ReadAll(transform.NewReader(bytes.NewReader(data), decoder))
if err != nil {
    log.Fatal(err)
}
fmt.Println(string(utf8Data))

Here we use the transform and io/ioutil packages in the standard library to convert the encoding method, and convert all data to UTF-8 encoding.

Through the above methods, we can avoid the problem of garbled characters during Golang programming, thereby improving the stability and maintainability of the program.
