使用jQuery上传非拉丁文名称文件

Question

I have simple form to ajax-upload files to server.

Here is input event listener:

$(document).on('change', '.js-file', function(event){

    sendFile(event);
});

And here is the function that actually uploads the file:

function sendFile (event) {
    var files = event.target.files;


    var action = '/ajax-upload-files/';
    var data = new FormData();

    $.each(files, function(key, value)
    {
        data.append(key, value);
    });

    $.ajax({
        url: action,
        type: 'POST',
        data: data,
        cache: false,
        dataType: 'json',
        processData: false,
        contentType: false,
        success: function(data){

        },
        complete: function(data) {
        }
    });
}

It wors fine with all kinds of files, except those with non-latin characters in the file name, e.g. Максим.jpg

The data is being sent to server, as I see in Chrome network. But when I try to dump $_FILES on server, it seems to be empty.

var_dump($_FILES) //array(0) {}

I don't really understand what's wrong - contentLength of the request header is much smaller then it should be - it looks like file was not appended to form for some reason.

I finally managed to upload non-latin name file. Have to read it as binary and send as binary.

HTML:

<input class="js-file" name="filename" type="file">

And js

//Handler in input
$(document).on('change', '.js-file', function(event){
            var file_name = $(this).attr('name');


            var reader = new FileReader();
            var f = event.target.files[0],
                nameArr = event.target.files[0]['name'].split('.'),
                extension = nameArr[nameArr.length-1]; //here we can check if extension is allowed

            reader.onload = function(e) {
                var contents = e.target.result;
                contents = contents.split('base64,')[1]; //we need only encoded part

                sendFileAsBinary(file_name, extension, contents);
            };

            reader.readAsDataURL(f);


        });

And sender:

function sendFileAsBinary(file_name, extension, img) {

    $.ajax({
        url: '/ajax-upload-files/',
        type: 'POST',
        data: {
            name: file_name,
            img: img,
            extension: extension
        },
        dataType: 'json',
        success: function(data){


        },
        complete: function(data) {

        }

    })

}

And php code to decode image:

 $name = $this->_getParam('name');
 $extension = $this->_getParam('extension');
 $computedName = $name . '.' . $extension;

 $fileContent = base64_decode($this->_getParam('img'));

 file_put_contents($fileContent, $computedName);
