[JENKINS-6960] URLEncoding problem with 'from' parameter

[timja]

Way to reproduce:

• log out if you're logged in
• create a job with non-ascii characters in the name
• go to the project's page (so now you're at https://hudson/hudson/job/K%C3%B6r%C3%B6k/ for example)
• click on the login link, the link will be something like this: https://hudson/hudson/login?from=/hudson/job/K%C3%B6r%C3%B6k/ )
• log in
• and see the 404 error page from the url:
  https://hudson/hudson/job/K%F6r%F6k/

liryc17:

I have a job which name is "création d'un test" and the link in the main page is :

création d'un test

as you can see, the quote character ' is not URLEncoded with %27.

This make a loading error when trying to see the job's configuration page (variable).

Another error is when I try to delete the job.
Nothing happens when I click on the delete project link on the job page loaded with url ..../job/cr%C3%A9ation%20d'un%20test/ BUT the delete action link works on the job page loaded with url .../job/cr%C3%A9ation%20d%27un%20test/
