Ok, i got the answer by my self. 
The chars of not printable and non-ascii are represented as Hex. 
To convert it back:

PUBLIC FUNCTION url_encode(url_string AS String) AS String
  DIM i AS Integer
  FOR i = 0 TO 32
    url_string = Replace(url_string, "%" & Hex$(i, 2), Chr(i))
  NEXT 
  FOR i = 127 TO 255
    url_string = Replace(url_string, "%" & Hex$(i, 2), Chr(i))
  NEXT 
  RETURN url_string
END
