Thanks for the reply. It’s very likely that the page contains images, borders, background, etc., so I can recognize all the text are missing. But neither of text missing nor text garbled suggests me how to fix it. I’d try another browser, then give up viewing the page.

But the scenario is still not a security issue. Whether it’s a security issue or a feature makes a big difference for us to discuss how important this change is, so I’m interested in knowing what kind of security aspects showing fallback glyphs can help, when considering browser rendering.

Any thoughts?
