URL encoding
posted on 2014-07-11 11:29:42

URL encoding (or 'percent encoding') describes encoding special characters in Uniform Resource Identifiers (URI's). On the difference why it is called URL encoding but is used for URI's, well... just accept it. Or read here.

Most likely you just want to know this:

!   #   $    &   '   (   )   *   +   ,   /   :   ;   =   ?   @   [   ]
%21 %23 %24 %26 %27 %28 %29 %2A %2B %2C %2F %3A %3B %3D %3F %40 %5B %5D

or this:

        newline        space     "   %   -   .   <   >   \   ^   _   `   {   |   }   ~
%0A or %0D or %0D%0A    %20     %22 %25 %2D %2E %3C %3E %5C %5E %5F %60 %7B %7C %7D %7E
