Special Symbols missing

[OverTook]

$a = 1111;
$b = 2222;
$c = 3333;
$d = 4444;
EasyForms::sendForm($player, new class("Test", "Test for me.\n\n" . 
        "Your Name : " . $a . "-" . $b . "-" . $c . "-" . $d . "\n\n" . 
        "If right Click [Y], or [N].\nSry for my bad eng.", "y", "n") extends ModalForm{
              public function onSubmit(Player $player, $response) : void{
                     if(!$response){
                        $player->sendMessage("§8[ §7§lAlert §r§8] §rThx.");
                        return;
                     }
                     $player->sendMessage("§8[ §7§lAlert §r§8] §rThx2"); 
              }
});

I expected the following.

Test for me.

Your Name : 1111-2222-3333-4444

If right Click [Y], or [N].
Sry for my bad eng.

But this is what we actually received.

Test for me.

Your Name

If right Click Y, or N.
Sry for my bad eng.

Where did the following characters disappear?

[ ] : -

sorry for my bad eng 👍

Maybe client side bug
