url-hexify-string does not handle non-latin
characters. According to
http://www.w3.org/International/O-URL-code.html , the string
must be converted to hexadecimal UTF-8 and every hexadecimal
byte must be prefixed with a % character. Rewritten
url-hexify-string is below:

(defun url-hexify-string (str)
    "Escape characters in a string."
    (mapconcat
     (lambda (char)
       ;; Fixme: use a char table instead.
       (if (not (memq char url-unreserved-chars))
           (if (< char 16)
               (format "%%0%x" char)
             (let ((ins nil))
               (mapconcat=20
                (lambda (charhex)
                  (progn (setq ins (not ins))
                  (if ins (concat "%" (char-to-string charhex))
                    (char-to-string charhex))))
                (format "%x" char) "")))
         (char-to-string char)))
     (encode-coding-string str 'utf-8) ""))
