For example, the script title cannot be rendered properly, and it can be avoided.

There shall be fallback fonts if the default font does not support the language of text.

Looks like an issue is on your side.

Looks fine to me as well.

Oh. I just found that it is not about the font family CSS rule. It is about the "lang" used in the page.

I use Brave. When I set the text container element with css rule -webkit-locale: "zh-TW";, it becomes normal again.

I do not have further information on this topic.
