I haven't tried every game engine, but at least the browser provides "key.code" to get the code (fixed numeric position) and has for at least a decade, and every programming language I've use to detect key presses offers it.

You're the second person this week to mention Star Wars Squadrons, I think it's a sign I need to check it out. I played Rogue Squadron and TIE Fighter as a kid, so it'll be fun to see how Star Wars games have progressed. I usually avoid EA games, but maybe it's worth breaking that for this game.
