Does Yoast support Chinese character?

As tittle.
I try to configure it.

It always show as following.

The keyword / phrase bangkok shutdown 曼谷 圍城 封鎖 集會 遊行 抗議 黃衫軍 does not appear in the page title.
The keyword doesn’t appear in the first paragraph of the copy, make sure the topic is clear immediately.

If there is only bangkok shutdown, it works.
Please kindly let me know it.

Many thanks,
Occu.
