Had a similar problem to: forums.ankiweb.net/t/unicode-alt-code-input-on-linux-not-working-with-new-launcher/65532 but it seems the issue was closed.
I am on Linux Mint 22. I recently updated Anki from a 2024 version (not sure, if there is a way to check, just let me know) to Anki 25.09.2.
Previously, I used to be able to type Unicode characters using CTRL + SHIFT + U and an underlined U+ would appear that would allow me to type in the Unicode hexadecimal string. This would generally work in every editor in Anki, from the editor for creating a new card to the editor present when browsing cards or the typing prompts in some of my flashcards. However, I am unable to perform this now in any of the editors in Anki after the update and pressing CTRL + SHIFT + U followed by the hexadecimal string does nothing, it only types the normal string (as if I didn’t press CTRL + SHIFT + U). I tried using CTRL + U but that just enables the underline formatting.
I have verified I can use Unicode characters in the Anki launcher (the CLI) but after booting, I cannot. I can still use Unicode characters in every other application. Based on that, it might be a Qt problem but I am not sure how to troubleshoot that.
I have tried disabling the add-ons and restarting Anki and my computer and it still does not work.
Any ideas?

I don’t think so. On debian trixie it works perfectly fine for me. And it worked on debian 12 as well judging by daes comment in your linked topic (see [Unicode alt code input on Linux not working with new launcher - #4 by dae](https://forums.ankiweb.net/t/unicode-alt-code-input-on-linux-not-working-with-new-launcher/65532/4)).

It was automatically closed because there was no activity on it.

1. ~~Can you use Ctrl+Shift+u outside of Anki?~~ You already confirmed this.
2. Can you try the results that you get on the internet for searches like “linux mint control shift u not working”? E.g. this one: [https://forums.linuxmint.com/viewtopic.php?t=320998](https://forums.linuxmint.com/viewtopic.php?t=320998)
3. Have you changed your keyboard related settings in any way (maybe indirectly by updating your distro)?
4. Does it not work anywhere in Anki or can you find a window where it works?

I wanted to share my solution in case anyone stumbles upon this and has the same issue (not able to use CTRL+SHIFT+U for Unicode characters and press CTRL + ENTER to switch languages to Korean using fcitx5).
While I am not sure exactly the root cause (maybe someone else knows), I essentially followed this guide on the Anki installation documentation: [Install & Upgrade - Anki Manual](https://docs.ankiweb.net/platform/linux/installing.html#system-qt-versions).
Based on the guide, I removed the specific directory, extracted the compressed file, created `system_qt` file, and installed the `python3-pyqt6.qtwebengine` package.
After installing Anki via the `./install.sh` script, I then received the following error after installing and trying to run `anki` via the command line (the same error as also received when just trying to run `anki` in the compressed folder without installing via `./install.sh`):
```auto
~/Downloads/anki-launcher-25.09-linux$ anki
Traceback (most recent call last):

ModuleNotFoundError: No module named 'PyQt6.QtQuick'
```
Just based on the error, I decided to just download the `python3-pyqt6.qtquick` package. After installing and trying to run `anki`, it worked and I was able to not only do CTRL + SHIFT + u to type unicode characters based on the code point within the Anki GUI, but I was also able to switch languages to Korean using `fcitx5` within the Anki GUI.
