permitted_uri_chars

I am having a problem with uri's

The URL i am requesting is http://localhost/Ci_1.6.0_test/type/news+personal, which works fine but in the controller i look at segment 2 and it equals 'news_personal' it automatically converts the + to and underscore. This is a problem as i want to explode the string on the + not the _ as i would like to be able to use something like this http://localhost/Ci_1.6.0_test/type/news...al_reading.
