Why ci url does not support Chinese

[eluser]yinzhili[/eluser]
So far as I know, you can't use Chinese characters in any URLs.Such as:

Code:

http://example.com/login/username/张三

It won't work. You can use:

Code:

http://example.com/login/username/<?php echo urlencode('张三');?>

And in login.php you could use this to get the value of the parament:

Code:

<?php
$username=$this->uri->segment(3);
$username=urldecode($username);
?>

Try this.
