I tried this now and I can generate a key for example-ä.se 6Ld8VRETAAAAALRXFNxmjEeVzbg2y5vdWv7THwJz
will publish a full working example soon
EDIT 1
Here's a git repo for code the same as on heroku
Well, this is not a complete fix because I used herokuapp.com as a domain, so example-ä.herokuapp.com becomes a subdomain and works
(however, when I tried earlier, he created a key for example-ä.se too, but when loading the page in captcha it gives an invalid domain , it turned out that this was the original problem, I thought you could not generate a key for this domain )
Will try to perform a full fix
EDIT 2
Btw you can also specify your domain IP address, check the discussion
For me, the free heroku account does not provide an ip domain, so it's hard for me to test it
Also I read this thread
It turned out that if I specify the list of domains as soon as com , it accepts. In your case, just specify se as domains and it should work, google does not check the exact url, it just checks the domain

Hope this stoken also at the stoken approach
