I guess we are stuck at disagreement. I did see the text. If it bothered me that much, I would write a proxy that passed HTML through iconv tool before serving it to user (with a dictionary to remember setting for each site). But more likely, I would stop visiting such site or complain to the owner. Situation doesn't get better by covering up errors.
