Question

PHP

Hello, I need help when downloading a song with a Russian name on the site, it gives out a different encoding such as u0422u0438u043fu0448u0435u043c u0421u0430u0448u0443u043a, I know what the problem is in my php, $audio = json_encode( $audio ); but I need it to remain and Russian letters appear.
What can be done about it? I will be grateful for any help :)

Answer 1

$audio = json_encode($audio, JSON_UNESCAPED_UNICODE);
