I did this

curl "" -vL

returned data :
< HTTP/1.1 301 Moved Permanently

I expected the following

On web browsers, the url redirect to 0080S00006F80400R70720S and the space in that url is handled. But on curl the space is not url encoded which cause the website to return :
HTTP/1.1 400 Bad Request

I can reproduce this problem when the redirect is to an absolute URL. If it redirects to a relative path curl URL encodes path components with embedded spaces. I'm on it.

... to make it handle for example (RFC violating) embeded spaces.

I don't think this is a regression. I think it never worked with spaces in absolute URLs.

It should be noted that spaces are not allowed in URLs per RFC 3986 which is the primary spec defining curl's URL parsing.
