It would probably help if you gave a real example, a REST call that returns
something (presumable JSON or XML) that contains a URL that is problematic.
FWIW, the following do also work
('https://en.wikipedia.org/wiki/' , 'Česká republika' urlEncoded) asUrl.
('https://en.wikipedia.org/wiki/' , 'Česká republika' urlEncoded) asUrl
retrieveContents.
