Sometimes some characters bypass fcitx5 #419

wanghuibin0 · 2021-12-25T16:04:52Z

Describe the bug
I am using fcitx5 to input Chinese in emacs.

When I input Chinese, I expect that fcitx5 captures all characters that I type and converts them into Chinese characters.
But sometimes one or more English characters bypass fcitx5 and go to the screen directly.

For example, I want to input "文件". So I enable fcitx5 and type "wenjian".
Sometimes, only "wejian" is captured by fcitx5, the missing "n" goes directly into the application such as emacs.

Such a problem does not occur every time. But it occurs unpredictably, which is quite annoying.

To Reproduce
Steps to reproduce the behavior:

Open emacs app
enable fcitx5
Try to type whatever you like

Expected behavior
The typed characters are all captured by fcitx5.

Desktop (please complete the following information):

Desktop: archlinux+i3wm
Display server type: X11

I only know sometimes this happens on xim + chromium. but with that being said, the issue is not on the fcitx side but on the emacs side. I don't know if you have anything special on the emacs that triggers this because I don't know other people report the same problem.

To help workaround your issue, actually I suggest to switch to emacs's pgtk branch. I heard that it's recently merged into emacs mainstream. It makes emacs use gtk for rendering and input method, which essentially use the gtk im module for input method.

Since you're using arch, try this AUR package: https://aur.archlinux.org/packages/emacs-pgtk-native-comp-git/ . Let me know if you have the same problem with pgtk enabled emacs.

wanghuibin0 · 2021-12-29T05:42:44Z

OK, I'll try emacs-pgtk.
Thanks for your help!

wanghuibin0 · 2021-12-29T07:46:07Z

Very glad that emacs-pgtk works well.
Thank you again.
