At level 0, the application can't rely on PATH_INFO at all. It can't do 
routing without deployment help from rewrites. It may choose to generate 
only links in query-string form instead of routed paths.

At level 1, the application can use routing, as long as any strings 
inserted into the generated links are slugged down to simple ASCII 
(without %2F or control codes).

At level 2, the application can output full Unicode paths, knowing it 
will be able to retrieve unmolested non-ASCII path segments for 
matching. This is needed for routing Wikipedia-style Unicode URLs (eg. 
in IRI form, http://en.wikipedia.org/wiki/日本).

At level 3, the application can put any byte sequence in a path part and 
retrieve it without it having been changed. Probably not a good idea for 
an application to require this, but it's here for completeness.
