问题
Here's the thing. I have friendly urls like
http://site.com/blog/read/мъдростта-на-вековете
http://site.com/blog/read/green-apple
The last segment is actually the friendly title of the blog article. The problem is when I try to pass that segment to the database, the cyrillic fonts turn into something like %D1%8A%D0%B4%D1%80%D0%BE%D1%81%D1%8 and couldn't match the database record. In the address bar in my browser it looks normal (мъдростта-на-вековете) but if I choose 'copy url location' the last segment again turns into these strange characters. I'm using CodeIgniter and everything is set to UTF-8.
Please help! :(
回答1:
The text is just being encoded to fit the specification for URLs.
Echo out the data to a log to see what you are actually trying to pass to the database.
You should be able to decode it with urldecode.

The above answers are ok, but if you want to use routing with cyrillic it isn't enough. For example if you have http://site.com/блог/статия/мъдростта-на-вековете you will have to do something like this:
In config/routes.php: $route['блог/статия/(:any)'] = "blog/article/$1";
In system/core/URI.php , in the function _explode_segments(), you can change
$val = trim($this->_filter_uri($val));
to
$val = urldecode(trim($this->_filter_uri($val)));
This will solve the above problem plus controllers and functions.

Actually, Firefox is cheating you here: the URL actually is url-encoded, but is shown as if it wasn't. So copy-pasting and retrieving it on the server will have the URL encoded.
(Not sure if other browsers behave in the same way.)
