How can the BOM (Byte Order Mark) in UTF-8 encoded files impact the display of special characters in PHP applications that use Ajax for data submission?

The BOM (Byte Order Mark) in UTF-8 encoded files can cause issues with special characters in PHP applications that use Ajax for data submission. To solve this problem, you can remove the BOM from the UTF-8 encoded files before processing them in your PHP application. 

function remove_utf8_bom($text) {
    $bom = pack('H*','EFBBBF');
    if (substr($text, 0, 3) == $bom) {
        $text = substr($text, 3);
    }
    return $text;
}

$file_contents = file_get_contents('file.txt');
$file_contents = remove_utf8_bom($file_contents);
// Process the file contents without the BOM
