How do I match japanese characters using IDN regex?

Based on this post link text

i came up with a regex for javascript

\b(([\w-]+:\/\/?|[\w\d]+[.])?[^\s()<>]+[.](?:\([\w\d]+\)|([^`!()\[\]{};:'".,<>?«»“”‘’\s]|\/)))

this one matches urls like

• http://google.com
• http://www.google.com
• google.com

It fails for google, but when I used japanese characters like 功功.jp it fails.

• www.功功.jp开发者_运维百科
• http://www.功功.jp
• http://功功.jp

These match. What should I change so that 功功.jp also matches.

Very slight modification made here has it working for me:

/(([\w-]+:\/\/?|[\w\d]+[.])?[^\s()<>]+[.](?:\([\w\d]+\)|([^`!()\[\]{};:'\".,<>?«»“”‘’\s]|\/)+))/
