Before I could upgrade all my sites to 2.2 latest upgrade to 2.2.1 is out. I found at my site here everything is perfect there is no character display problem. However at my main blog there are some funny character, e.g. apostrophe has turned into funny characters! I didn’t do anything at the config.php file to fix that since I have no ftp access from here. I just edited the post again and it turned OK now, just wondered why?
