Golang exports csv garbled characters

When using Golang to export CSV files, if garbled characters occur, you need to pay attention to the following aspects:

1. Character set encoding issues

Character set of CSV files The encoding usually uses UTF-8, so when exporting a CSV file, you need to ensure that the character set encoding of the file is consistent with the source code. The character set encoding can be set in the source code using the following code:

// 设置字符集编码为UTF-8
w := csv.NewWriter(file)
w.Write([]string{string("字段1"), string("字段2"), string("字段3")})
w.Flush()

2. Content encoding issues

When exporting a CSV file, you must ensure that all content is encoded in the same way as the file The character set encoding is consistent. If the content is encoded incorrectly, it can result in garbled files. The following code can be used to solve the content encoding problem:

// 设置字符集编码为UTF-8
file, err := os.Create("data.csv")
if err != nil {
    log.Fatalln("Failed to create file", err)
}
defer file.Close()

w := csv.NewWriter(transform.NewWriter(file, charmap.Windows1252.NewEncoder()))
w.Write([]string{string("字段1"), string("字段2"), string("字段3")})

3. Handling of special characters

In CSV files, some special characters may affect the normal reading of the file, such as Commas, double quotes, etc. Fields containing special characters can be enclosed using "..." or '...' so that they are processed correctly. The code example is as follows:

w.Write([]string{`"特殊字符,处理方式1"`, `'特殊字符,处理方式2'`, string("字段3")})

The above are some possible reasons and solutions for garbled characters when exporting CSV files. If you have any other questions, please leave a message in the comment area and we will answer you in time.
