Thanks for your report and your research! However, the upstream commit which is said to fix it is huge, and does not apply to the version of the source in Debian/Ubuntu. mozc is packaged at Debian. It would be great if you could file a bug to Debian too, so the maintainer can consider the best way to deal with it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931554 Title: Japanese hiragana input fails after first keypress in anki To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mozc/+bug/1931554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1931554] Re: Japanese hiragana input fails after first keypress in anki
** Package changed: anki (Ubuntu) => mozc (Ubuntu) ** Description changed: This was working fine before I upgraded to 21.04. Since then I am seeing what appears to be a bad interaction between the Japanese input method and anki or anki's underlying widget set. Hiragana input works by typing the roman characters that make up a word. After typing a few characters you'll get suggestions for the correct Japanese text. For example, I type aimasu, which will appear on screen as あいます, with the suggestion that I probably meant 会います which I can select from a drop-down. Since upgrading to 21.04 when I type the first character into the anki "Add card" dialog I see the first hiragana あ appear correctly, the "i" character appears to be ignored and maybe is the place things fail, - followed by the roman characters for "masu". In other words, aismasu + followed by the roman characters for "masu". In other words, aimasu appears on the screen as あmasu as opposed to the correct あいます. The drop- down I would normally expect to see appears only for the あ character and then gets stuck on the screen until I switch back to an English input method and back again to Japanese. I can't enter the full Japanese text, although my web browser and terminal window are able to accept Japanese text without any issues. My input method shows in the UI as "Japanese (Mozc)" with input mode "hiragana".

[Bug 1931554] Re: Japanese hiragana input fails after first keypress in anki
As far as I can tell line 207 above fails due to the text being the empty string "", but the cursor_pos and anchor_pos are both 1, so line 207 is trying to assign the string from position 1 to position 0 within the empty string. That makes some sense given how the input method works. At the time of the crash, a single character has been entered, but it hasn't been committed to the dialog as yet. That said I still don't understand whether it is Anki, QT, or mozc that is fundamentally at fault. My guess is mozc despite this working in other contexts I have tried. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931554 Title: Japanese hiragana input fails after first keypress in anki To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/anki/+bug/1931554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
