Go标志：Windows上的尾部斜杠转义引号[关闭]

Need to validate and clean user input of a path. When a user enters the following command line:

 app.exe -f "C:\dir with space\"

The the flag value has the last quote escaped, so it's string value is:

 C:\dir with space"

What do you guys recommend for a clean approach at sanitizing user input for a directory/path? Regex, or does Go have a library for dealing with this similar to filepath.Clean(), but removes trailing quote?

Edit: The cause is documented here: https://github.com/golang/go/issues/16131

For example,

package main

import (
    "fmt"
    "path/filepath"
    "runtime"
    "strings"
)

func clean(path string) string {
    if runtime.GOOS == "windows" {
        path = strings.TrimSuffix(path, `"`)
    }
    return filepath.Clean(path)
}

func main() {
    path := `C:\dir with space"`
    fmt.Println(path)
    path = clean(path)
    fmt.Println(path)
}

Output:

C:\dir with space"
C:\dir with space

 pkgDir   := flag.String( "f", "", "REQUIRED: `pkgdir` the root directory of the package")
 flag.Parse()

 *pkgDir = strings.TrimRight(*pkgDir, `'"`)
