it's probably the character set used by the connection.
If you use Dynamic connections to create the database connection, you can set the character set to UTF-8, other wise, you would need to edit the connection file to force it to use the UTF-8 character set.
for example, in the Connection/PowerCMSConnection file, line 9 would look like this:
$PowerCMSConnection = mysql_pconnect($hostname_PowerCMSConnection, $username_PowerCMSConnection, $password_PowerCMSConnection) or trigger_error(mysql_error(),E_USER_ERROR);
add the following code after that:
inline editing is not supported. It may be a feature that is available in CKEditor 4, but you would need to manually code the ability to use it. you would need to hand code the editor to show on the page for only admins, and also to update the database. We could help you with this in a premiere support ticket, but it is not supported by data bridge. We will probably be adding his feature to a future upgrade.
