Make google Recaptcha work with special characters in the domain name
问题 I was setting up an API key for a site with the swedish charachter ä in the domain name (http://sälja.io) but it did not initialize the recaptcha. Then trying an api key for the equivalent url http://xn--slja-loa.io which worked when reaching the site from http://xn--slja-loa.io but not http://sälja.io. Then I found the secure token which should work on all domains. It initialized the recaptchas on all domains and was also working on all tested domains, except the one with ä in it . https:/
