• Go to the New job page.
• For the name of the job, enter 'Contrôleur' (French for 'controller').
• Hudson then attempts to open page
  http://localhost:8080/job/Contr%C3%B4leur/configure
  and I get the following error:

However, URL http://localhost:8080/job/Contr%F4leur/configure seems to work OK.

My recommandation: prevent the user from entering those special characters. As
seen with issue #929, allowing those special characters might have other issues
down the road.
