Both key and scankey has some problems on AZERTY keyboards about love HOT 4 OPEN

What OS and love version are you testing with? If you're on Linux, are you using the love AppImage or love installed through a package manager?

This is the last LÖVE version, from package manager (tested on Arch x86_64 and Manjaro Aarch64 (ARM64), but after some verifications, the problem come from libSDL2, verified on other libSDL2 application (TIC-80) and libSDL2 API, I will try to report to libSDL2, and when it is resolved, will close it here.

Make sure your version of SDL2 is up to date (the latest release is 2.28.5, and 2.30 is coming shortly). If you use love's AppImage instead of relying on system package manager dependencies, then it'll use SDL 2.28.5. I believe there have been several fixes to scancode detection on Linux recently, so I think there's a high chance using the latest version will solve your issue if you have an older version.

ArchLinux packages are always up to date (that's a rolling release), its goal is to upstream bugs instead of adding patch, as most as possible. So yes, this is the latest release, but the bug is very old. I think to invest more time in SDL improvement anyway, encounter some other part where it is behind in term of functionalities on Linux, despite it was first created for Linux around 2000 (lot of good work made since).
