PHP opendir() not displaying Cyrillic folders?

Question

PHP

The task is to develop a file manager, started.
The first thing I encountered was that opendir does not display folders in Russian, and accordingly does not go to them.
Here is the code, in the documents directory is the "New Folder" folder. It displays it like this:

Here is the code

self::$path = $_SERVER['DOCUMENT_ROOT'].'/public/cloud/documents/';

        $dir = scandir(self::$path);
        $files = array(
            'dir'  => array(),
            'file' => array()
        );

        foreach($dir as $el){

            if(is_dir(self::$path.$el)){
                $files['dir'][] = $el;
            }else{
                $files['file'][] = $el;
            }
        }

Used iconv:

iconv('utf-8','Windows-1252',$_SERVER['DOCUMENT_ROOT'].'/public/cloud/documents/');

In general, I looked for information, they explained it to me easier to translate into transliteration. But this is inconvenient, tell me how to act in this situation.
The script is spinning on win 8 (open server) but upon completion of course CentOS
Upd.
The crux of the matter is that opendir does not open folders with Russian letters! How to solve it?

Answer 1

Well, the Russian encoding is only not 1252, but 1251, as far as I remember

Answer 2

Are meta-charset explicitly specified in the page code? It won't work in webkits otherwise / won't always work.

Answer 3

I understand that the question was asked more than three years ago, but there is still no answer.
You have an error in the iconv function, you need to swap the encodings.
False: Correct : iconv('utf-8', 'Windows-1252', string)
iconv('Windows-1251', 'UTF-8', string)
