--- Comment #9 from Huanyu Liu <1293660441 at qq.com> ---
Full font-embedding is especially disastrous if you are writing CJK
annotations. The default Noto Sans CJK on my computer will transform a 30KB
tiny file into a 20MB monster, making the text annotation tools practically
unusable (unless you choose a more lightweight CJK font such as Droid Sans
Fallback, which also takes up several MB).
What's worse, since Noto Sans CJK is a CID font, I cannot find a way to subset
it using existing free tools such as GhostScript or PyMuPDF. It will end up
either garbled or with errors.
