Or if they both exist.

POLA/UI-Consistency argues for escaping '%' as well.

The paste-from-browser problem is much harder: metacharacters in URLs
confuse command interpreters. We can't solve this problem. It doesn't
make sense to introduce inconsistency to svn over a problem that we
can't solve.

Let's say someone *does* paste a URL-encoded string onto the command-line:

$ svn co http://www.foo.com/repo%20name -d dir

They'll get an error message. It will be:

svn_error: #21097 : <RA layer didn't receive requested OPTIONS info>
  The OPTIONS response did not include the requested activity-collection-set.
(Check the URL again; this often means that the URL is not WebDAV-enabled.)

This is probably good enough to convince the user that pasting URL-encoded
data is not such a good idea ("Check the URL again").
