Go の「encoding/csv」パッケージは、CSV ファイルの書き込みおよび読み取り時に二重引用符のエスケープをどのように処理しますか?

<code class="go">import (
    "encoding/csv"
    "fmt"
    "os"
)

func main() {
    f, err := os.Create("./test.csv")
    if err != nil {
        log.Fatal("Error: %s", err)
    }
    defer f.Close()

    w := csv.NewWriter(f)

    s := "Cr@zy text with , and \ and \" etc"

    record := []string{
        "Unquoted string",
        s,
    }
    fmt.Println(record)
    w.Write(record)

    // Quote the string to escape double quotes
    record = []string{
        "Quoted string",
        fmt.Sprintf("%q", s),
    }
    fmt.Println(record)
    w.Write(record)

    w.Flush()
}</code>

[Unquoted string Cr@zy text with , and \ and " etc]
[Quoted string "Cr@zy text with , and \ and \" etc"]

<code class="go">func readCSV() {
    file, err := os.Open("./test.csv")
    defer file.Close()
    cr := csv.NewReader(file)
    records, err := cr.ReadAll()
    if err != nil {
        log.Fatal("Error: %s", err)
    }
    for _, record := range records {
        fmt.Println(record)
    }
}</code>

[Unquoted string Cr@zy text with , and \ and " etc]
[Quoted string Cr@zy text with , and \ and " etc]
