Can't share a url in cyrillic: http://вода-серебряная.рф. My site uses facebook.com/sharer/sharer.php to achieve that. The url is already transformed to punycode (http://xn----7sbbdcmja7ed0aci5rc.xn--p1ai/) with FB at this step.
When I click Share Link, an error is returned with the following message: Could not post to Wall. The message could not be posted to this Wall.
I've also checked the url at developers.facebook.com/tools/debug and it returned the following error: Error Linting URL: An internal error occurred while linting the URL (see the result).
Is it a FB bug or how can I fix this?
Facebook isn't currently set up to support Internationalized domain names. If you file it at the Bugs Tool, it'll be tracked as a feature request there.
