I needed URLs like this:

Code:

http://mydomainname.com/news/1,the-title-of-the-article-with-id-1.html

The variables in config.php and routes.php are set like this:

$config['permitted_uri_chars'] = 'a-z 0-9~%.,:_-';
$route['news/([0-9]+),([0-9a-z-]+)']="news/viewnews/$1";

And it works fine. However changing the "permitted_uri"chars" variable to any of these:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-,';
$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-\,';

results in the preg_match() error.
