APFSでファイル名がUnicode正規化されないことを検証する

VerifyUnicodeNormalization.swift

let filenames = [
    "\u{30D1}\u{30D1}",                 // パパ
    "\u{30CF}\u{309A}\u{30CF}\u{309A}", // パパ
]

let fm = FileManager.default
let baseURL = fm.urls(for: .documentDirectory, in: .userDomainMask)[0]
filenames.forEach { filename in
    let url = baseURL.appendingPathComponent(filename)
    let fd = fopen(url.path, "w")
    fputs(url.path, fd)
    fclose(fd)
}

let files = try! fm.contentsOfDirectory(atPath: baseURL.path)
let filenameAndEscaped = files.map {
    ($0,
    $0.unicodeScalars.map({
        "\\{\(String($0.value, radix: 16))}"
    }).joined())
}
filenameAndEscaped.forEach { print($0) }

Hi,
i'm affected too with your bug https://openradar.appspot.com/31265273
Is there any way (prefered without XCode) to check which app or which app's file-store contain the files, so that i can backup again?
