It could have anything in there, including any mix of encodings and there's been no enforcement of any encoding, so there's no way of knowing what they are. If you've had, for example, webapps that let people paste word documents into them, you potentially have different encodings used in different rows of the same table. If your current data is like that then you're probably looking at doing some (manual) data cleanup to work out what encoding your data is really in, and converting it to something consistent rather than a simple migration from ascii to utf8.
