Try with an external library, the bundled library is compiled without CJK.

Any external library can be recommend? And I encountered a situation where there was no CJK before, and it gave such an error instead of a direct crash. error: cannot find builtin CJK font

You need MuPDF library installed, then use extlib tag, and if needed add static or pkgconfig tags.
