Error : After a wordpress upgrade we started to get all kinds of weird symbols in our posts, including  and ’. I figured it was a character encoding mismatch problem.
Solution:
You have to comment out two lines in your wp-config.php file (found in your main blog directory). These are the two lines:
define(‘DB_CHARSET’, ‘utf8′);
define(‘DB_COLLATE’, ”);
Comment them out like this:
//define(‘DB_CHARSET’, ‘utf8′);
//define(‘DB_COLLATE’, ”);
Fixed our problem.
