I continue to be somewhat confused by logic that suggests that storage benefits from being in the U-label form. A-labels are almost de facto normative since they work withIDN-aware and IDN-unaware appllications. IDN-aware applications should be able to generate the corresponding U-label for presentation. IdN-unaware applications. Won't even recognize a U-label domain name as valid IWoild think. Consequently, storage in A-label form seems the rational choice. If you disagree, it must be because you see a flaw in the reasoning above. Can you clarify? V

There are two sides here, the protocol correctness and
the content correctness. By content correctness, I mean
whether the link e.g. goes to the intended page.
Completely impossible to check with punycode, of course.
