Description

HttpClient upload file with chinese name, but server cannot accept it.

How to reproduce

client:

$client = HttpClient::create();
$formData = new FormDataPart([
    'files' => DataPart::fromPath(__DIR__ . '/中文.txt')
]);
$response = $client->request('POST', 'http://localhost/test/fileupload.php', [
    'headers' => $formData->getPreparedHeaders()->toArray(),
    'body' => $formData->bodyToIterable(),
]);
dd($response->getContent(false));

server:

var_dump($_FILES);

The right result should have $_FILES, but no.

Possible Solution

I log formData info use this: file_put_contents(__DIR__ . '/a.txt', $formData->toString());, and get

Content-Type: multipart/form-data; boundary=RGWgOk4l

--RGWgOk4l
Content-Type: text/plain
Content-Transfer-Encoding: 8bit
Content-Disposition: form-data; name="files"; filename*=utf-8''"%E4%B8%AD%E6%96%87.txt"

中文
--RGWgOk4l--

When I change
Content-Disposition: form-data; name="files"; filename*=utf-8''"%E4%B8%AD%E6%96%87.txt"
to Content-Disposition: form-data; name="files"; filename="中文.txt"
or Content-Disposition: form-data; name="files"; filename="中文.txt"; filename*=utf-8''"%E4%B8%AD%E6%96%87.txt"
It correct uploaded!

But I dont known how to fix this
