My Japanese website has an international domain name: http://xn--mcki2eq4ryb.hobby-site.org/
Depending on which browser you use, this may or may not be displayed as http://ガーデニング.hobby-site.org/ When I use the code generated by the tweet button code generator (http://twitter.com/about/resources/tweetbutton) I get the following message when clicking on it: URL required 'url' parameter does not contain a valid URL. So, I have tried specifying the URL explicitly as an urlencoded query parameter like so: http://twitter.com/share?url=http%3A%2F%2Fxn--mcki2eq4ryb.hobby-site.org%2 ... but I get the same message. A page with a tweet button that demonstrates this exact problem can be found here: http://xn--mcki2eq4ryb.hobby-site.org/introducing-gardening-hobby-site.html The URL http://xn--mcki2eq4ryb.hobby-site.org/ IS a valid url, so it seems like this is a bug in the tweet button. Please could you fix it as soon as possible?
