I would treat the opening questin mark as part of the word and include it in the typeface indicator. That seems in accord with the spirit and intent of the foreign language rule, especially since there is no reason here to do otherwise. No mention is made of the typeface of the question mark. In fact, no mention is made of the question mark at all--just the word that is associated with. The question is not even in a different typeface, but the same color as the other words in the sentence. This is only a visual device to draw attention to the word that follows.
