Answer 1

Use this function instead of fopen while reading but not while writing

function utf8_fopen_read($fileName) { 
    $fc = iconv('windows-1250', 'utf-8', file_get_contents($fileName)); 
    $handle=fopen("php://memory", "rw"); 
    fwrite($handle, $fc); 
    fseek($handle, 0); 
    return $handle; 
}

In your case

$d = utf8_fopen_read("chat.txt", "r");
 $content=fread($d,filesize('chat.txt'));
 $bn=explode('||',$content);
 foreach($bn as $bn)
 echo $bn.'<br>';

Try this

$content = iconv('windows-1250', 'utf-8', file_get_contents($fileName));
$bn = mb_split('||',$content);
foreach($bn as $b)
     echo $b.'<br>';
