But it has been mentioned that heuristics are not infallible, and this method's heuristics are no exception. It does a good job overall, but I've found that it usually misinterprets UTF-8 format text.
Yes, I know that all the guess jobs can fail. I was starting to be excited when started reading your reply but if it usually misinterprets UTF-8, that's a pretty significant problem...
