This is an encoding issue,  caused by either your PHP/server or database settings. 

What is the PHP version on your new server?
What is the encoding of your new database and tables?

It is likely you're using a PHP version bigger than 5.3 on your new server. With PHP 5.4 the default encoding changed to UTF-8. 
This is because with ((https://www.php.net/ChangeLog-5.php#5.4.0 PHP 5.4)) the ##default_charset## is set to UTF-8, and this change is not taken into account in versions prior to  WackoWiki R5.4.x.

Please switch your PHP version to 5.3.x or upgrade your WackoWiki to a newer version.
