dash not allowed in custom routed uri since 1.7?

[eluser]thenetmonkey[/eluser]
Hello,

I've just encountered a strange problem since upgrading from 163 to 170: the router isn't letting me use a - (dash) in my uri segments anymore.

The following route is setup in config/routes.php:

Code:

$route['feed/(:any)'] = '/feed/index/$1';

with this rule in place, the following URL used to work:
http://www.wineconsigners.com/feed/wine-searcher

Now, however, I get a 404 page thrown even before the constructor for my feed class is built ( I put a show_error( 'feed' ); in my feed constructor just after the parent::Controller(); call and I still get the 404 )

The URL works fine when I take the dash out, so I've just told my vendor to use the new feed URL of http://www.wineconsigners.com/feed/winesearcher and it's working fine.

I asked around on IRC and someone named [OES] suggested I try using this route:

Code:

$route['feed/(.*)'] = '/feed/index/$1';

and that regexp didn't work either.

My permitted_uri_chars looks like this:

Code:

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

this was the same permitted_uri_chars I used in 163 and it worked there.

I tried doing a diff between the 163 Router.php and 170 Router.php lib, but there are only a couple differences, and none of them look like they have anything to do with handling dashes, but I could be wrong.

I'm running PHP Version 4.3.10-22 on Apache 1.3.33.

Has anyone else ran into this when the upgraded to 170?
Is there a known fix?
Should I file a bug report?

Thanks in advance for your help.
