Add encoding parameter

Hi Meagan,

I noticed that Paul had added a few new rows to the program spreadsheet, so I tried to run the script again, and it broke because one of the new names includes non-English characters. As a result, I had to add the encoding parameter to get it to run properly.

In addition, I made a small addition to the merge_rows_on_name method because the final file was missing the headers from the applicant sheets.

I updated your shared Google doc with the newest sheet and the updates that Mike requested (additional columns for date data and conditional formatting). Can you please review it when you get a chance, and let me know if it all looks OK?

Thanks,
Taryn
