When this happens, you need to send a correction on the question. There are some older quizzes that have issues with some symbols. An editor can try to fix the problem if you alert them to it. (But first, if possible, you should try to play the original quiz from which the question came. The problem may already have been fixed in the original question, but some of the games use cached questions that still have problems. In that case, you just have to live with it until the caches get refreshed.)

That's all, folks!
