encoded _HTML_ ? what you will need is hpricot (which is amazing :-)

require 'rubygems'
require 'hpricot'

Hpricot("hi&gt;there&lt;", :xhtml_strict => true).to_plain_text # => 
"hi>there<"

But! from your example seems like you don't want to unescape html but 
the url:

require 'cgi'

CGI.unescape "hi%5Bthere%5D"
=> "hi[there]"

Greets!
