Apparently you have some data which is outside the range of ASCII character

If you choose ANSI then only ASCII data will be saved... Choose UNICODE if
you are not sure...
or choose both and compare the files you get.

Is this something that will affect my data. I am using this list for the
purpose of sending emails to in Outlook.
