Old style string literals and their escapes can often be avoided. The typical Go solution is to use a raw string literalhere:
通常可以避免旧式字符串文字及其转义。典型的 Go 解决方案是在此处使用原始字符串文字：
fmt.Println(`"`)

Don't say Go doesn't leave you options. The following all print a quotation mark ":
不要说 Go 不会给你留下选择。以下都打印一个引号"：
fmt.Println("\"")
fmt.Println("\x22")
fmt.Println("\u0022")
fmt.Println("2")
fmt.Println(`"`)
fmt.Println(string('"'))
fmt.Println(string([]byte{'"'}))
fmt.Printf("%c\n", '"')
fmt.Printf("%s\n", []byte{'"'})
// Seriously, this one is just for demonstration not production :)
fmt.Println(xml.Header[14:15])
fmt.Println(strconv.Quote("")[:1])
Try them on the Go Playground.
在Go Playground上试一试。
