Python: IDNA does not round-trip

Dobro jutro.

Evo, nov dan, nov izziv.

Tokrat gre za URL, ki je zapisan v IDNA obliki.

Zanima me, kakšne so opcije, da ga konvertam v (i guess) v unicode.

import idna;

# link = "https://www.xn--elolivoespaol-skb.es/es/queso/174-quesos-la-casota-queso-manchego-artesano-marantona-viejo.html";

link = "https://xn----ctbhcbk8fd.xn--p1ai/product/chernosliv-bez-kostochek-1-kg-uzbekistan";

print(link);

link = link.encode("utf-8");

link = link.decode("idna");

print(link);

Error:

UnicodeError: (
    'IDNA does not round-trip',
    b'xn--p1ai/product/chernosliv-bez-kostochek-1-kg-uzbekistan',
    b'xn--p1ai/produ2ct/chernosliv-bez22-kostochek-21-kg-h5bemi'
)

Super. Sem spremenil, da konverta samo domeno in deluje.

Hvala.
