It’s how non-Latin Unicode domain names are encoded, in this case one made out of Japanese characters. I suppose it depends on the browser whether or not it shows them.

Two of my favourite tools!

I like Void, it feels a little more like a BSD. But I’ve only really used it for experimentation, no idea what it’s like as a daily driver.

You could also try an actual BSD. OpenBSD has a very clear style and direction which I like but be careful when partitioning, they have their own ‘disklabel’ system. Updates are really streamlined with syspatch and sysupgrade.

NetBSD had a nice TUI installer. It may appear a bit less focussed on its aims but has a lot going for it: many supporter platforms, a friendly community, etc.

There’s also FreeBSD, DragonflyBSD, possibly more but I don’t have much experience with those.
