I’ve updated pandoc with both the changes you suggested.  chinese is now used with babel, and the template now includes babelfonts.  With the new code you should be able to make this work without a filter.

I wrote a small lua filter that inserts raw `\foreignlanguage`/`\begin{otherlanguage}` commands for chinese in the same way as pandoc by default does for other languages, and it works just fine. So maybe the best solution would be to simply add chinese to Lang.hs?

For other languages that are defined, the LaTeX writer produces `\foreignlanguage{}{}` commands, but in this case it produces only `{言}`. Thus, the only possibility is to resort to `CJKmainfont`. The issue is that this switches on xeCJK for the whole document, which has undesirable side effects (mainly concerning spacing around punctuation characters). Thus, I have to introduce manual `\makexeCJKactive`/`\makexeCJKinactive` commands in my markdown source. For short passages of Chinese, it is actually desirable not to use xeCJK, but simply babel, as with other scripts.

With the old polyglossia system, IIRC, it was possible to use the `fontfamilies` metadata entry to define `\chinesefont` etc. for additional scripts. But this does no longer work with babel (if I’m not missing something).
