Unicode Alt Code Input on Linux Mint Not Working w/ New Version

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).

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
  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?
