Samuti ilmnes viga Fcitx5 kasutamisel hiina keele sisestamiseks, kui kasutasin AppFlowy uusimat versiooni AUR-i hoidlas. Kasutan X11.

我不知道keyboard_service_widget.dart文件修改的作用，我的参考：github.com/AppFlowy-IO/AppFlowy@f5cc6521fb
delta_input_on_replace_impl.dart内如果replacement开头出现空行，则无法正常处理输入法，但是replacement在non_delta_input_service.dart的apply方法内执行了format方法，导致无法在delta_input_on_replace_impl.dart内判断开头时是否是空格
但是用方向键移动插入指针到前面的字符不会产生响应，就像我下面这个视频展示的一样

https://github.com/AppFlowy-IO/AppFlowy/assets/31309149/b44039f7-c26e-49bf-a8a5-0c96e48ac3ec

但我不懂dart和flutter,不知如何修复，并且delta_input_on_replace_impl.dart的修复一定不符合规范和运行逻辑，我希望能帮我修好。
这是我的修改：068b7948ab8380f3c7ef655f9891a4f92a8ba518

可以的话我希望能修复输入问题，插入指针移动问题需要修复的话，也可以联系我，我能够提供测试设备和环境。

修复fcitx5和wayland下无法输入中文问题

我的英文不好，用中文回答了十分抱歉。

可以帮助我吗？@annieappflowy @LucasXu0

@XGX1 Really appreciate your testing and help. I'll try your changes and see if I can fix it on Linux as soon as possible.
