Tested with wine-4.18-112-g717109ce79:
1. $ wine64 notepad
2. Switch to Chinese Pinyin input method, and try to type something

You will find that candidate didn't display, though you still can type some
Chinese characters into notepad with the input method.

I didn't see similar on macOS 10.14, so I think this is a Catalina special
issue.
