I just tried the following versions from the GitHub releases page:
- 2.1.39, 2.1.38, 2.1.37, 2.1.36
- then I skipped to 2.1.33
- then I skipped to 2.1.22
- then finally I skipped to 2.1.15 (the first version with binaries on GitHub)
It’s broken on all of them. T.T
Up until yesterday I was using Flathub Anki v2.1.38 (Flathub—An app store and build service for Linux), and it displays Korean characters flawlessly. (Iinputting them, on the other hand, is another matter but that’s a Flathub-Anki-specific bug, and therefore not relevant here, I think.)
I decided to switch to the official binary to get the latest version (2.1.40), at which point I discovered this bug and reported it here.
