API update of 8-bit character domain names


I’m using ddclient in order to update my DNS records when my public IP changes.
This is working fine except from the domains that I have with 8-bit characters.
I’ve tried both the 8-bit representation (gottöl.se) and the 7-bit variant (xn–gottl-mua.se)
but I get “No domain ID found.” in both cases.
