What is the issue with the URL Standard?

Version 16.0.0 (2024-08-30) of Unicode Technical Standard #46 has been released. It fixes some previously reported issues:

More IDNA roundtrippability issues #760
The Processing 4.3. step (after Punycode decode) fixes this issue:

If the label is empty, or if the label contains only ASCII code points, record that there was an error.
IdnaTestV2.json "xn--xn--a--gua.pt" test case problem #803
The test in question is now correctly labeled in IdnaTestV2.txt:
```
xn--xn--a--gua.pt; xn--a-ä.pt; [V2, V4]; xn--xn--a--gua.pt; ; ;  # xn--a-ä.pt
```

So I think it's worth upgrading to that standard:

Reference the new 16.0.0 Unicode Technical Standard #46 in the Normative References section.
In the WPT update the IdnaTestV2-parser.py tool and the IdnaTestV2.json test file. I have opened a PR for this: URL: Update IdnaTestV2 to UTS46 16.0.0 web-platform-tests/wpt#48301

The text was updated successfully, but these errors were encountered:
