Different levels of escaping for PATH_INFO on different servers

[whateley]

Camping is inconsistent in what it puts in the PATH_INFO variable when responding to a URL containing Unicode characters.

For example, "/tag/μformats":

When running under Mongrel, @env.PATH_INFO is "/tag/%CE%BCformats".

When running under WEBrick or FastCGI, @env.PATH_INFO is "/tag/\316\274formats".

[why]

I agree. Also, lighttpd should escape spaces as %20 rather than a plus sign.

This patch normalizes the PATH_INFO. Is it what you want ? Or should the adapter be responsible of the work ?

Fixed in [231] with a shorter solution than in the previously shown patch.
