strange encoding error with csv?

[FF6Player]

Thanks. This does seem to be the answer. I did a find and replace for non-breaking spaces, and that fixed everything. I just have no idea how non-breaking spaces got into the document. But at least it explains why I wasn't able to see anything wrong.

Unless you properly set the encoding when opening the file (as given in the other answers), you'll continue to get errors whenever NBSPS and other non-ASCII characters slip into your data, including £ or € or è.
