In my experience Punycode support in browsers varies greatly depending on the phishing[1] mitigations in place, making them quite unreliable in practice unfortunately. I'm pleasantly surprised about SMTPUTF8 being a thing though. Yeah nobody uses it, but I thought email had zero UTF-8 support so it's at least better than nothing, I guess.
