CJK characters in chat all render as D

We kindly ask that you complete the questions below. With this information, we can add it to our database for investigation.

Issue Description:
I live in Japan, but my game is in English. When I match with random players, they are usually from Asia. Apparently, they can chat with no difficulty. However, all text they enter display as what seems as DDDD to me. I.e. my version of the game does not seem to support CJK characters; but theirs apparently does. I would very much like to be able to read what they are saying. Similarly, though not as pressingly, I cannot use an IME. If I type text elsewhere and paste it into Darktide, it does work (though, again, it renders as a series of D characters).

I believe I had the same issue with Vermintide games, but it would be nice if it could be resolved.

Steps to Reproduce:
For example, paste 日本語 or 한국어 into chat. Screenshot attached below.

Happens on EU servers as well, I’m guessing when someone uses unsupported keyboard language
