The Python code of ``'%' + hex(ord(<character>))[2:]`` escapes a

Reserved characters : ";/?:@&=+$,"

Have special meaning in URIs and must be escaped if not being used for

|
their special meaning
|

Data characters : letters, digits, and "-_.!~*'()"
|
|
Unreserved and do not need to be escaped; can be, though, if desired
|
|
Control characters : 0x00 - 0x1F, 0x7F
