Well, I'm not familiar with url-*.el but there seems to be no
function to encode a url containing non-ASCII characters such as:
"http://банки.рф/";
In emacs-w3m[1] there are some encoder functions:

;; An encoder used for a full url string:
(w3m-url-transfer-encode-string "http://банки.рф/";)
 => "http://xn--80abwho.xn--p1ai/";

;; An encoder used for a string that is a part of url:
(concat "https://ja.wikipedia.org/wiki/";
        (w3m-url-encode-string "日本語ドメイン名"))
 => 
"https://ja.wikipedia.org/wiki/%E6%97%A5%E6%9C%AC%E8%AA%9E%E3%83%89%E3%83%A1%E3%82%A4%E3%83%B3%E5%90%8D";

Those two encoded urls will work.
