What version of Universal Email do you have installed? This looks like it could be an old bug where the $charSet wasn't being set properly when you have an older version installed. You may have to install the latest version of Universal Email and open up and set the charset value for the Email to fix this problem.
The secon part you would fix by opening the Store Cart Summary in database server behavior on the confirm page. Find the ReferenceID column and make sure it is marked as a text column.. also make sure the database has it marked as a text column.
