I was recently interested in Chinese philosophy research. However, I find it difficult to show ancient Chinese characters properly in my ubuntu's firefox.
The test page is https://ctext.org/font-test-page
I tried and have installed many CJK supporting fonts. I have also applied my font preference in Firefox->Preference->Language and Apperance->Fonts and Colors->Advanced. My Fonts for Simplified Chinese is set as:
Serif: WenQuanYi Micro Hei
Sans-Serif: Noto Sans CJK SC
Monospace: Noto Sans Mono CJK SC
But still, the test page is not passed. This is what I saw:
Thanks in advance for any help.
