MODx, MIGX and Cyrillic?

Question

MODX

Good day!
The problem is this: if you enter data in the admin panel in TV with the MIGX type, then the Cyrillic alphabet is entered and displayed normally, but it is written to the database as

"color":"\u0410\u043c\u0435\u0440\u0438\u043a\u0430\u043d\u0441\u043a\u0438\u0439 \u043e\u0440\u0435\u0445"

instead of human Cyrillic, and this is important, because the customer exports the entire database of goods in .csv and then works with it.
I tried both utf_general_ci and utf_unicode_ci base encoding, nothing changed.

Answer 1

I asked myself, I answer myself:
in the /core/xpdo/xpdo.class.php file, on line 2365, the toJSON function is declared, which now looks like this:

public function toJSON($array) {
        $encoded= '';
        if (is_array ($array)) {
            //  if (!function_exists('json_encode')) {
            //    if (@ include_once (XPDO_CORE_PATH . 'json/JSON.php')) {
            //      $json = new Services_JSON();
            //    $encoded= $json->encode($array);
            //  }
            // } else {
                $encoded= json_encode($array, JSON_UNESCAPED_UNICODE);
            //}
        }
        return $encoded;
    }

Answer 2

It looks like json.
