Subject: Square brackets in URI

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello

 I was trying to handle some user entered URL/Is and came across the
following problem: How do I handle URIs with brackets in the path part?

require 'uri'
u = "http://my.wonder.fu/ll url [with brackets]"
ue = URI.escape u
puts "Escaped. The brackets stay the same:"
puts ue

begin
  up = URI.parse u
rescue URI::InvalidURIError
  puts "Parsing the unescaped string breaks."
end

begin
  uep = URI.parse ue
rescue URI::InvalidURIError
  puts "Even parsing the escaped string breaks."
end

Linux wigowyr 2.6.20-16-generic #1 SMP Tue May 29 17:59:55 CEST 2007
i686 GNU/Linux

I saw the URI::REGEXP::PATTERN::UNSAFE already includes ...::RESERVED
characters, but the way it is used confused me.. maybe it's to late for
me tonight.

Any ideas?

Niklas
