As I noted in a response to Nils earlier in this thread, 
Firefox/Webkit/Opera don't actually require authors to percent-encode 
brackets and spaces in data URIs. (not sure whether that's correct per 
spec or not).

For example
   data:text/html,<i>here is some italic text<i>
works just fine in all three.

So that makes it quite easy to hand-author data URIs, in fact. (aside 
from this "#" gotcha)
