Fox Weiqi Not Showing Chinese (or CJK) Characters

[psygo]

I'm able to run the Fox Weiqi client (the foreign version) perfectly with Wine: https://www.foxwq.com/soft/foreign.html

And I can type and see CJK characters just fine on apps.

Is Wine not able to access these characters by default?

It's also happening on my Mac (Sequoia).

I'm hosting a bounty over this on that Stack Exchange.
