There are some compatibility issues with the most popular Chinese input methods

Is there an existing issue for this?

• I have searched the existing issues

Flutter Quill version

9.3.6

Steps to reproduce

1type a Chinese charater with Sogou Chinese input method
2choose blod or any tool that will add a effect on the content you will type in the editor
3type one more Chinese character with Sogou Chinese input method

Expected results

Sogou Input Method should have some recognition functions for the characters you have already typed, such as guessing the content you want to input based on the typed characters. But the actual situation may very well be different from this, and you need to verify it yourself.

Actual results

When you use Sogou Chinese input method, bolding, italics, and other effects will not affect the newly typed Chinese character, but will affect the previous character you typed. When you input Chinese characters after a custom embedding, the embedding will crash directly, unless you enter a space or any English character as a placeholder before entering a new Chinese character.
