// I recently disabled charset mask related code for V7+ games, thinking
// that it should never be needed there. Well, I missed on case: In this
// method, it could potentially still be used. Now the question is:
// Does this actually ever happen? Basically, drawString is called from
// two spots: First off, from drawVerb, which I *think* is not used for
// V7+ games (but I am not 100% sure), and secondly from printString().
// The latter is much harder to predict. Maybe in some obscure place it
// is used after all?
//
// Hence I am adding this error message, hoping that either somebody
// triggers it (at which point I can investigate), or, if nobody ever
// triggers it, we can assume that it's safe to keep this error even
// after the release.
//
// TODO/FIXME: Remove or update this hack before the next release!
