Punycode site in 'Callback URL'


#1

If i enter my IDN site callback url:
https://блог.фанфрог.рф/wp-content/plugins/wordpress-social-login/hybridauth/?hauth.done=Twitter
in App Manager, i’m getting The client application failed validation: Not a valid callback URL format. error.
Seriosly, it`s almost 2017 now and still there are services with punycode-related problems…:confused:

There’s a workaround in this post.
