Expected behavior

It seems I can now apply only one font family to title, headlines, posts, codes.

Both of the following ways don't work

  title:
    external: true
    family: Roboto Slab|Noto Serif SC
    size:

  title:
    external: true
    family: Roboto Slab, Noto Serif SC
    size:

I've viewed #1238 and it seems okay to specify multiple global fonts. I'm not sure if I made a mistake somewhere.

If it's indeed not supported now, I think it will be great if users can apply more than 1 font family. Especially for those who writes both Chinese and English often.

Yes! I also need this feature, so the Chinese and Latin characters can be set with different font-family properties.
