B4J Question B4J JavaFX Webview: unicode icons-symbols are ... wrong

HI, All
I have found that B4J Webview distorts the UNICODE symbols, say looks like , looks like .

And if the source symbol is colorful - WebView all made B&W. My web-pages are for sure with

<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />

Click to expand...

And Chromium-based web-browsers are OK with all these symbols.

javafx.version=19.0.2.1, javafx.web is WebKit v613.1.

Any ideas ? Fixable ?
