Having special characters in URLs in CodeIgniter -

Having special characters in URLs in CodeIgniter -

i want have urls like

http://www.example.com/(*.)

but codeigniter not allow me that. when seek access urls 404 error (and requested page exists).

i know can set allowed characters in url, thought encoding it. however, if this:

http://www.example.com/<?php echo rawurlencode(string) ?>

or even:

http://www.example.com/<?php echo rawurlencode(rawurlencode(string)) ?>

i still got 404. why that? '%'s allowed characters, why won't work? , can prepare it?

when trying pass urlencoded strings uri generate error if encoded string has /, codeigniter seek parse segment, rendering 404, need utilize query strings.

$string = rawurlencode(string)

http://www.example.com/class/method/?string=$string

then on method

use get

function method() { $this->input->get('string'); }

codeigniter url encoding routing special-characters
