The funny part is that to this day, many places still show ¥ instead of \ in Japanese locales, even with UTF-8. Starting with the Windows command line prompt.

And on the opposite side, in a terminal, on macOS, hitting the ¥ key inputs a \, but not in other applications (including vscode), where you need to use option+¥ for a \.

(BTW, I have no idea how to type ¥ in the terminal on macos with a Japanese keyboard)
