ERROR: Korean characters with Chinese characters

I am currently using Scrivener for Windows, Ver. 0.0.29

It worked really well with Korean language until I typed some Chinese characters between Korean characters. (See attached screen shot.)
That’s when an error occurred and the program was shut down automatically.
I opened the file again, and there are only Korean characters saved. (See attached screen shot.)

Korean keyboards have a key to switch Korean to Chinese, and that’s how I typed the Chinese characters. And they are different from “Chinese” Chinese characters.

Please kindly take a look at this. Should you need anything I can do with this matter, just let me know.

Thank you.
