Dustbin is also UK English, and I (Canadian) don’t actually know what “visually a dustbin” looks like. In Japanese/English spoken in Japan, “dustbox” is also a term sometimes used for what I would call a small garbage can.
Do they also localize the folder path? It’s “./Trash” in US english
A dustbin is I believe called a trashcan in North America, ie: it’s what the Classic Mac OS Trash / “Wastebasket” icon shows. A (usually) metal cylindrical container for rubbish with a lid, usually kept outside. Nowadays in the UK mostly replaced by wheelie bins…
It's still internally .Trash, as that isn't user visible I suspect it's the same for all localisations of Mac OS.
