Read Turkish from MS SQL server R2 table

I modified the code so it reads from a CSV file and writes to another CSV file (excel file saved as .csv). I pasted the code bellow because I don't know how to attach a zip file here. Try copy and paste these characters into the original .csv file: ú ü ø ? ? Ñ Ö æ ä å ã ë ( modify the file path as necessary)
