Thank you Vic, adding the ENCODING 'latin1' option to the COPY command worked
perfectly.

If you don't mind a follow up to your reply, I have tried to understand the
different character sets and collations, but I guess I still have a lot to
learn. Your suggestion did not even come close to crossing my mind because the
MySQL table and database are encoded in UTF8. I assume the conversion to latin1
happened because I was putting the MySQL query output into a locally stored
text file? Regardless, can you point me to some reading that would have clued
me in that e9 is not a UTF8 character? Or is the clue the fact that it was not
preceeded with 0x00?
