<ALT>+key are displaying something wrong or are beeping and aren't displayed like in other terminals.
FYI I use a Spanish keyboard, the key 帽 is displayed correctly, so I don't think it has to do with the layout in terminal, but all that is <ALT>+帽 which should give ~ beeps as wrong inputs do.
<ALT>+麓 which should give {, instead returns '', and pretty much all other combinations with <ALT> are beeping and not displaying anything.
Put macos_option_as_alt no into your kitty.conf. This will let you use the alt key to type unicode characters again instead of passing the alt key directly to the shell or whatever you're running.
Thank you! That did it.
