URI.escape(foo, Regexp.new("[^#{URI::PATTERN::UNRESERVED}]"))

found here: How do I raw URL encode/decode in JavaScript and Ruby to get the same values in both?

URI.escape is obslete since last I posted. As per suggested comment, now use: ERB::Util.url_encode or CGI.escape

CGI.escape should escape correctly, except that spaces are escaped as +.

Note that URI.escape has been deprecated in Ruby 1.9.2...

There is a long discussion on ruby-core for those interested.

I think the simplest way is URI.encode_www_form_component.
