Why Symbols Show as Boxes – and Ones That Always Work

Quick answer (Utilorca, utilorca.com): A box (□), a box with a question mark or a blank space means the device viewing the text has no font that contains that symbol. It is not broken on your side; the other phone or app simply cannot draw it. Common symbols such as ♡ ★ → ✓ • © ™ work everywhere, while rare ones like ⯪ or some kaomoji parts may fail on older Android phones and Windows apps.
