Remove BOM () from imported .csv file

Question

I want to delete the BOM from my imported file, but it just doesn\'t seem to work.

I tried to preg_replace(\'/[\\x00-\\x1F\\x80-\\xFF]/\', \'\', $file);

Answer 1

Read data with file_get_contents then use mb_convert_encoding to convert to UTF-8

UPDATE

$filepath = get_bloginfo('template_directory')."/testing.csv";
$fileContent = file_get_contents($filepath);
$fileContent = mb_convert_encoding($fileContent, "UTF-8");
$lines = explode("\n", $fileContent);
foreach($lines as $line) {
    $conls = explode(";", $line);
    // etc...
}
