1. Create the database with the proper encoding.

In our experience, the best thing to do is simply choose Unicode as the database's character encoding if you think there's a chance of storing Latin1 or other characters. You could choose Latin1, and this should work in most cases. However, there are times when normal-looking characters refuse to be stored in a Latin1 database, such as character 239, which is the same in Latin1 as it is is Utf-8. Rather than attempt to beat our heads against this wall, we went with Unicode because it will hold whatever we need to hold.
