I find Xah Lee's pages quite useful

And other curiosities like:

I recently got a file from a colleague who thought she was typing unicode
but the encoding was not UTF-8 so the file was mojibaked.

So, yes things dont (cant?) default to ASCII any more but that does not
mean unicode (UTF-8) just works.

In emacs if you see a 'U' in the modeline left corner, its unicode.
Else you have some debugging to do.
