webview上显示的表情符号是问号吗？

<meta charset="UTF-8">

body {
    font-family: 'Segoe UI Emoji', 'Apple Color Emoji', 'Noto Color Emoji', sans-serif;
}

WebView webView = findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDefaultTextEncodingName("utf-8");

let webView = WKWebView(frame: .zero, configuration: WKWebViewConfiguration())
webView.load(URLRequest(url: URL(string: "https://yourwebsite.com")!))
