For better or for worse, in French, one is supposed to insert a non-breakable space before various punctuation (
? : ! ;).
I can hand-code
s into questions, but they get escaped in comments.
Is there any chance you could 'escape' the escaping for us? :)
UPDATE I've rolled a user-script to convert Ctrl-spaces to non-break-spaces (inspired by Frédéric's answer below).
