Ok friend clearly has a character problem.It has problem also with è, ì and ò
Try this solution:
Fixing the Character Encoding Mismatch Problem in WordPress
Step 1) Open the ‘wp-config.php’ file in a text editor such as notepad (the wp-config.php file can be found on the directory where you installed WordPress).
Step 2) Find the following two lines and comment them out:
Code:
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');
They should look like the following after you comment them out:
Code:
//define('DB_CHARSET', 'utf8');
//define('DB_COLLATE', '');
Step 3) Now upload the updated ‘wp-config.php’ file to your webhost (overwriting the old one).
This character encoding problem can happen after a database upgrade too so it doesn’t hurt to keep this trick in your mind just in case.
