A space before a question or an exclamation mark. Can it be correct? is affirming what I always use, but now some translators at my office said that I always need a space before. I am sure they are French or something but before I answer them, I would like to see some British source confirming it.
UPDATE: No, Wikipedia is not authoritative unless it has a link to a publication that is. The people I need to correct are likely native English speakers who sat too long next to French translators or something. I need some heavy tome to throw at them :)
UPDATE: The translators ate their words. All is well in the world.
