A couple of users have reported this problem before and while I have to admit I still don't know what causes it, I can tell you how to fix it. What's happening is that the charset gets changed for some strange reason and the new setting displays characters wrong.
To fix it, open MySmallList with a good text editor or if you're using TextEdit make sure you open the file with the 'Open' command and choose 'Ignore rich text format'. Then look in the header of the template for "fcharset0" and change that to "fcharset77". Save the template and the export should work fine for all characters.
