According to standard, conkeror uses converted to utf-8 URLs. But sometimes (e.g. mediawiki in non-latin
languages) encoded url isn't readable enough. This patch tells conkeror to decode URLs
(mini-buffer/mode-line/history autocompletion), when network.standard-url.encode-utf8 is set to 'false'
(like Firefox-based browsers do).

May be it's quick and dirty, but works for me like a charm :)
