Can you handle that on the application side

Unfortunately not

If this is a bug, please provide steps for reproducing it; the exact components you are using;

1. Add Pinyin - Traditional Chinese language keyboard in your system
2. Navigate to Fundamental NGX documentation website on Combobox Field: https://sap.github.io/fundamental-ngx/#/core/combobox
3. Go to first Combobox field example which has 5 fruits as options: Apple, Pineapple, etc.
4. Select any option from the Combobox field (ex: Apple)
5. Make sure to have activated the new Chinese language
6. In the Search Input after the selected option (ex: Apple) add any Chinese character without using copy paste of a Chinese character, it is needed to be typed from the keyboard (My guess is that here is the problem because a Chinese character if you type it from the keyboard, after you press a keyboard letter then you have to choose using a number what variant of that character you want to use. Also if you don't have any value selected the issue is not reproducible, this could be also a hint)
7. Then try to delete characters from search term of Combobox and you will see that the Combobox search term got into a broken state and is stuck (In the video attached after I made the same steps I was pressing Backspace continuously and couldn't delete the search term because it got stuck. Switching to another option of the Combobox didn't fix the state)
