Php function imagettftext () for writing text using emoticons

Question

I use the imagettftext function to write text on the image, but my text contains emoticons and it replaces the emoticons with a square square.

Here is my code:

$black = imagecolorallocate ( $main_img, 0x00, 0x00, 0x00 );
$font_path = "Arial.ttf";
imagettftext ( $main_img, 14, 0, 73, 685, $black, $font_path, $text );

Text:

test testt😘 Hello 👋💐 Those 👏  Mega x 👊❤️  Graphic 💋

I tried to change the font, which is "Arial Unicode", but its problem is not resolved.

How can I solve this problem?

Thanks in advance.
