libopusurl takes URIs, not IRIs. I looked into supporting IRIs, but 
somewhere in the middle of hand-maintained punycode domain whitelists I 
gave up.

In short: You need to URI-encode your string before passing it in. 
Proper handling of domain names requires something like libidn, which is 
built into libc on some systems, but by no means everywhere.
