Yes, it is, since around 1991. But still Japan has its Yen symbol
instead of the backslash, and its overbar instead of the tilde.
And so you shouldn't assume other countries are more advanced.

I agree we don't. I don't mind if "@", "$", "#", and even "~" are
officially part of URLs. But it's important we don't give the impression
that they can be easily typed everywhere and will pass though all
gateways if they actually don't.
