It's a big, complicated mess. I can't implement IDN support correctly because Python lacks UTS#46 and IDNA2008 support. I just found out that IDNA 2008 is not enough because it does not provide a case mapping. Lack of case mapping broke my fix for curl CVE-2016-8625.

At the moment IDN support is broken in a sane way: it just doesn't work and fails.

A partial fix will introduce security issues. lists "www.sparkasse-gieß" as a critical example. It's the domain of a German savings and loan bank.
