Subject: URI::InvalidURIError when using curly brackets

I've been experimenting using open-uri to retrieve HTML from various 
sites and have spent the past couple of days searching for an answer to 
my problem. One page I've been trying to access contains a GUID in the 
querystring and it has curly brackets around it. This is my code (I'm 
just using Google for this example):

require 'open-uri'

uri = 
URI.parse('http://www.google.co.uk/search?q={3F2504E0-4F89-11D3-9A-0C-03-05-E8-2C-33-01}')
html = open(uri).read()

But I get the following error:

 URI::InvalidURIError in DemoController#index

 bad URI(is not URI?): 
http://www.google.co.uk/search?q={3F2504E0-4F89-11D3-9A-0C-03-05-E8-2C-33-01}

 RAILS_ROOT: /code/public/../config/..

 /usr/local/lib/ruby/1.8/uri/common.rb:432:in `split'
 /usr/local/lib/ruby/1.8/uri/common.rb:481:in `parse'
 #{RAILS_ROOT}/app/controllers/scrape_controller.rb:10:in `index'

From what I've found, curly brackets aren't allowed in a Ruby URI 
(despite my browser being capable of handling them). I've tried encoding 
them with %7B and %7D but then the page is called with the encoded 
version, which in my case, the site isn't expecting and it doesn't work.

Is there a way to allow curly brackets in my URI? or another method to 
download HTML which does?

Thanks.
