Looks like HN broke the URL after submitting. Let's try again:

    https://ₛᵖ.ⓜ/

Here is the backup link:

▲ zenexer a day ago | parent | next [-]

That shows up as ₛᵖ.ⓜ, so a bunch of characters are missing.

HN seems to encode it as punycode when it shouldn’t; it skipped normalization.

	▲	pwdisswordfishq a day ago \| parent [-]
		Python 3 encodes the domain to xn--hkr-zdyy2ssn00g.mobi. Not that that works.

▲ a day ago | parent | prev | next [-]

[deleted]

▲ userbinator 18 hours ago | parent | prev [-]

Consider that a good thing; it seems HN is immune to Unicode confusion attacks.
