This is very much on purpose.

First, curl operates and URLs and spaces are not part of legal URLs.

curl is as liberal as possible to what URLs it accepts and lets through (as
long as it can extract the host name etc). It allows users to send lots of
weird things through to servers.

Having curl translate illegal letters into something else would take a lot of
effort and "intelligence" in the tool I much rather avoid. Is translation to
%20 *always* wanted when you pass a space in the URL? I doubt that.

Also (of course) different servers and different protocols will treat that
literal space differently.

That is what you are expected to do. If you want a %20 sent to a HTTP server.

Yes, but if you don't like what -O gives you, why not use -o and intent your
own file name?
