I caught the bad arithmetic on name length, but where is the byte order
mark coming from? My first line is plain English so far as I can see - no
umlauts or foreign characters.
first_name|last_name|email|city|state or region|address|zip

Is this an artifact of csv module output, or is it the data from
generatedata.com, which looks global? More likely it means I have to figure
out unicode ;'(
