File with utf8 encoding, create variable

$str = 'ааыв'; file_put_contents('ile.txt', $str , FILE_APPEND);

And writes the following to the file:

 ааыв

How to write to the file that the Russian characters were? ..

 mb_detect_encoding($str );// UTF-8

Via echo, it displays the string correctly, in Russian characters on the page.

     $str = 'ааыв'; file_put_contents('ile.txt', iconv('utf-8', 'windows-1251', $str) , FILE_APPEND);

      try the simplest solution: add it to the top:

       header('Content-Type: text/html; charset=utf-8');
