Query allows spaces

[gibsonf1]

I've been using (quri:uri to confirm something is a valid uri, however I just discovered that the query parse allows spaces. Is that permitted with the spec?

WEB> (quri:uri "https://github.com?bad=this is a test")
#<URI-HTTPS https://github.com?bad=this is a test>
WEB> (quri:render-uri *)
"https://github.com?bad=this is a test"
WEB> 

For now I've just added a space scan:

(defmethod ?uri ((item quri.uri:uri))
  (declare (optimize (speed 3) (safety 1) (debug 1)))
  (let* ((scheme (quri:uri-scheme item))
	 (host (quri:uri-host item))
	 (dhost (if host (split-string #\. host)))
	 (query (quri:uri-query item))
	 )
    (when (or (not query)(and query (not (ppcre:scan "\\s" query))))
      (when (and (member scheme '("http" "https" "ftp") :test #'string-equal)
		 (or (ppcre:scan "localhost" host)
		     (and (> (length dhost) 1)(> (length (car (last dhost))) 1)))
		 )
	t))))

My understanding is that, according to the spec, spaces aren't unreserved characters.

But perhaps it's not quri's goal to validate URIs.
