Error characters for CJK Radicals Supplement about common-chinese-radicals HOT 1 CLOSED

Hi @svenper, thanks for pointing this out, and sorry for the very late response.

I took your issue as an opportunity to adjust the source so that the file can be typeset on other systems than macOS.
With #2 first I replaced the commercial Myriad Pro font with the free Google Noto font.
For the CJK-Font, the source originally referenced the Kaiti SC font, which comes readily installed on macOS,
and which seems to be fairly complete when it comes to the CJK Radicals Supplement characters.

With the help of the GitHub Action for LaTeX I was able to try out different options for typesetting the document in a Linux enviroment (the underlying image uses Alpine Linux). At the end I could only get the radical characters you pointed out by using the original Adobe Kaiti Regular font (pulling it from a slightly dubious GitHub Repo). With both KaiTi oder STKaiti I get
nothing or the typical "unicode box" character.

Obviously, one could also use Noto Sans CJK for the entire document, but it's Chinese characters just don't look as
pleasing to the eye as the Kaiti-Characters 😄 .
