tornado.web.RequestHandler.get_argument returns a unicode string.
http://www.tornadoweb.org/documentation/web.html?#tornado.web.RequestHandler.get_argument
And urllib.urlencode converts unicode chars into string chars before percent-encoding them.
If an argument contains non-ascii characters, encoding(default charset is system dependent) results in UnicodeEncodeError.
