How to fix the encoding in when parsing?

Question

PHP

I'm trying to ask the page, but at the output I get the wrong encoding in cracks.
My site is on windows-1251
How to solve the problem?

$file = file_get_contents('https://tv.yandex.ru/213/channels/150?date=2016-04-12&period=all-day');
                    $dom = new DOMDocument('1.0', 'utf-8');
                    $dom->loadHTML($file);
                    $xpath = new DOMXPath($dom);
                    $schedule_items = $xpath->query('//div[@class="b-tv-channel-schedule__item"]');
                    $count = $schedule_items->length;

                    if ($count > 0) {
                        for ($i = 0; $i < $count; $i++) {
                            $item = $schedule_items->item($i);
                            $event_time = $xpath->query('a/span[@class="tv-event__time"]/span[@class="tv-event__time-text"]', $item);
                            $event_title = $xpath->query('a/div[@class="tv-event__title"]/div[@class="tv-event__title-inner"]', $item);
                            if ($event_time->length > 0 && $event_title->length > 0) {
                                $result .= $event_time->item(0)->nodeValue.$event_title->item(0)->nodeValue;
                            }
                        }
                        $teleprogramma .= "<h3><a href='#'>".$day_title."</a></h3><div>".$result."</div>";
                    }

Answer 1

My site is on windows-1251

$dom = new DOMDocument('1.0', 'utf-8');

Answer 2

convert the parsed data from utf8 to cp1251 with iconv

Answer 3

$result .= $event_time->item(0)->nodeValue . ' ' . mb_convert_encoding($event_title->item(0)->nodeValue, 'CP1251', 'UTF-8');
