and now look exactly what happens if you click on the second one for a short moment you see in the browser exactly the same a for the first, technically the second URL don't exist
the complete web was and is ASCII in case of domains and URLs on any lowlevel you only have punnycode and ASCII ecnodings
frankly the idea to allow special chars with technical tricks in domains was the largest mistake of the last 20 years
what people mostly do not realize is the security impact frankly i can register a punnycode domain for the user in the addressbar looking like a well known one and use that for phising attacks including a valid and accepted certificate - that is why not that long ago Firefox switched back to display Punnycode as the first attacks of this sort appeared, now it's again the dangerous way
