This post is about IDN (International Domain Names) and browser support in 2019, 5 years after the previous one. And hopefully, I’ll publish this one faster than the previous one.
Android
In 2019, Android has a lot of browser, but I only looked at a few of them:
Chrome

Firefox

DuckDuckGo
Not properly displayed (Yes, they have a browser)

It’s even worse, if you type only ‘tpî.eu’, you get redirected to the search engine, not the famous site. You need to type the full https://
But I get it, for a privacy oriented browser, it’s probably more important to prevent phishing than to play nice with IDN
iOS
Tests were done on an iPad.
Safari
