"I am not having any luck saving the file as CSV delimited" is not a helpful statement for troubleshooting.
Have you compared hexdumps when saved as "CSV (MS-DOS) (*.csv)" and "CSV (Comma delimited) (*.csv)", and if so, what were the exact results?
Does the "Text Import Wizard" pop up when you open the saved file? If not, you saved it as DOS csv.
Did you follow my advice about using "Save as" only, and absolutely no other "Save" dialog at all?
1. Create a test sheet with some French characters.
2. Go to "File > Save as", change the "Save as type:" dropdown box to "CSV (Comma delimited) (*.csv)", save as C:\Temp\Book1.csv.
3. Click "Save", click "OK" on the "The selected file type does not support workbooks that contain multiple sheets" dialog, click "Yes" on the "Book1.csv may contain features that are not compatible with csv ..." dialog.
4. Close the workbook, clicking Don't Save!
5. Open the file again, follow the "Text Import Wizard", and the French characters should show up correctly.
Finally, note that the "correct" way to save the file is determined by "elsewhere", not by being able to reopen it in Excel. "Elsewhere" decides which encoding it will use to open the file.
