Can you replace the default 2 sets of CJK fonts（NotoSansCJK-Bold，NotoSansCJK-Regular） in the installation package? The two sets of fonts I copied to the computer, simply can not be displayed, and the characters are not all.
I know that Google has provided a free CJK font. You can see it here. Https://www.google.com/get/noto/help/cjk/
As far as I know, this Super OpenType/CFF Collection contains all Chinese, Japanese and Korean characters.
