If you work with macOS or iOS users, you won’t be super surprised to see lots of “curly quotes”. They’re part of base macOS, no extra software required (I cannot remember if they need to be switched on or they’re on by default), and of course mass-market software like Word will create “smart” quotes on Mac and Windows.

I ended up implementing smart quotes on an internal blogging platform because I couldn’t bear "straight quotes". It’s just a few lines of code and makes my inner typography nerd twitch less.

Word (you know, the most popular word processor out there) will do that substitution. And on macOS & iOS, it's baked into the standard text input widgets so it'll do that basically everywhere that is a rich text editor.

> According to find in chrome, they are both considered the same character, which is interesting.

Browsers do a form of normalization in search. It's really useful, since it means "resume" will match résumé, unless of course you disable it (in Firefox, this is the "Match Diacritics" checkbox). (Also: itʼs, it's; if you want to see it in action on those two words.)
