An addition here, just to indicate the importance of setlocale() before the use of fgetcsv():
1. http://static.zend.com/topics/multibyte-fgetcsv.pdf
2. http://php.segmenta.ru/manual/en/fun...tcsv.php#62759
3. https://qiita.com/uedatakeshi/items/...c6b3e26a57c237

Perhaps it would be worthwhile to expose the desired setting of setlocale() to users so that they can choose/experiment both at export and import with the choice if their locale settings (either on the PC or in Zen Cart) are not ideal for CSV export/import.
