you need to know what diffrent between decode() & encode():
decode(param) param: any coding you used now , this func make any coding
to unicode
encode(param) param: any coding you want to use , this func make unicode
to any coding
now , your unquote(u'Kroati%C3%AB')`s coding is unicode , not utf8 , so you
can not make unicode to unicode , you should use
"unquote(u'Kroati%C3%AB').encode("utf8").decode("utf8")"
