Plus sign in URL
I am trying to import a site that has URL's/paths to files that have a + (plus sign) substituted for spaces so a url like example.com/path+to+image/folder/filename.jpg is coming back as 404 when SiteImport sends that instead of sending example.com/path to image/folder/filename.jpg which does resolve properly.
Is there an easy way to change a JS file or something in Site Import to sub a plus sign with space or %20?
Any advice is appreciated.
