(I've read #1441 and https://gitlab.com/libidn/libidn2/-/issues/25)

I think this should be supported but it seems that #1441 was never completely solved.

I did this

$ curl https://馃А馃.ws
curl: (3) Failed to convert 馃А馃.ws to ACE; string contains a disallowed character

I expected the following

It works in browsers and in wget. getting converted to the punycode https://xn--9s9hnf.ws/

curl/libcurl version

$ curl -V
