It would really help if Wikipedia (and dbpedia) redirect to the canonical
URL for a page, rather than serving up a 200.
In Wikipedia links, they never percent-encode brackets.
This is the ruby code that I use to convert page titles to URIs:
def escape_title(title)
URI::escape(title.gsub(' ','_'), ' ?#%"+=')
end
