Passing Japanese (non-Latin) URLs in Facebook "like" button URL fails

I think this is a URL encoding problem and not a bug in Facebook, but I'm really not sure.

This URL fails on the Like button: http://www.thefraser.com/2010/11/%E5%8B%95%E7%89%A9%E3%81%A8%E3%81%AE%E6%88%A6%E3%81%84

But this one works: http://www.thefraser.com/2010/11/carlos

What worries me is that the former URL fails in the Like button generator thing on Facebook, giving me an error saying 开发者_Python百科that there is no fanpage at the given URL.

I think the like button generator is glitched in the same way that my URL encoding is. I highly doubt that Facebook's like button itself is broken, since then everyone with non-English URLs would be complaining.

On the other hand, the same URL encoding for the same URL works for Twitter, so... hmm...

Any ideas for a workaround URL encoding? This one I'm using right now is Microsoft.JScript.GlobalObject.encodeURI(), which in theory behaves the same way as the JavaScript encodeURI function.

Strange question, I know, but any help would be appreciated. I'm on the verge of eating my cat alive.

Edit: other Japanese URLs, like this one:

http://ja.wikipedia.org/wiki/%E3%81%8F%E3%82%8B%E3%82%8A

don't fail with the Like button generator. Bahhh!

I look into the source code of the given page, it seems your URL has been escaped twice in the source code:

line 125 (%E5 has been converted into %25E5):

<iframe src="http://www.facebook.com/plugins/like.php?href=http://www.thefraser.com/2010/11/%25E5%258B%2595%25E7%2589%25A9%25E3%2581%25A8%25E3%2581%25AE%25E6%2588%25A6%25E3%2581%2584&layout=standard ...

Are you using PHP? Double check the code that generate this line. Post it here if unsure.

Nope, it's a bug.

Great. Their Bugzilla is also giving me an HTTP/500.
