I.buffer.top_frame.getSelection()

I don't know if that will handle sub-frames properly, but that is the
equivalent of what is recommended on the org-protocol webpage.

There are the standard global JavaScript functions encodeURI and
encodeURIComponent.

As a sidenote, looking at org-protocol, it is not clear what advantage
it offers over emacsclient -e.  Some of the protocols it actually
implements surely are useful, but the special filename interception it
does just seems like extra infrastructure for no gain.
