The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9' remain the same.
The unreserved characters - _ . ! ~ * ' ( ) remain the same.
The space character ' ' is not converted into a plus sign '+'.
All other ASCII characters are converted into the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the character code
All non-ASCII characters are encoded in two steps: first to a sequence of 2 or 3 bytes, using the UTF-8 algorithm; secondly each of these bytes is encoded as "%xx".
