We are in the process of finding a CMS to replace our current hybrid of 2 wordpress installs and about 1000 pages of flat content using static php files.

We have hundreds of existing urls that would need to stay the same and I am not able to find an allowed characters list for the url slug so that I can test.php to load. Currently it changes the url to testphp on save. Changing the urls of the site would be a huge hit to us with SEO.

Is there a place that we can allow the . to be present in the url so we can fake the php files? I have tried looking in the URLify library and am not seeing it there.
