Good advice. When I printed out the wins as well as the fails I found that the wins have odd characters too. So it's not that. Also was able to see some cases where there were trailing blanks after the filenames on the spreadsheet and fixing that helped a little. In other cases it's just manual error typing the spreadsheet, mostly random extra blanks.

chrestomanci I see your point about the alternation operator, but is seems to work as intended the way it is.
