Proposed Patch - url encoding all upper case...

[Brian Moran]

I'd like to propose that URI encoding be done using upper case 
characters instead of lower case characters. Both seem to be acceptable; 
I'm only requesting this since most of the other libraries that we use 
that do URI encoding use upper case characters.
