Spaces in url

[eluser]zebric[/eluser]
Hi!
In the configuration file as follows:

Code:

$config['permitted_uri_chars'] = 'a-z\s0-9~%.:_\-';

Using this routing:

Code:

$route['catalog/tm-([A-Za-z0-9_-]+)/model-([A-Za-z0-9_-\s]+)'] = 'catalog/model/$2/$1';

If use url with whitespace, for example:

catalog/tm-Brand/model-Cool apple

the routing rule is not working.


Who knows how to solve this problem?
Many thanks!
