how to convert UNICODE text file format into UTF-8 at the time of BEFIMPORT event script

Hi Experts,

I have 200 location in my FDMEE and i cannot expect all user to change their file format everytime they load it.

I want to convert the format of the file (irrespective of any file format) and save it to the same file name, before any process starts.

i set the file format in the SYSTEM settign as UTF-8, so if i import UNICODE it add space to each character in the file and all lines of records are skipped.

Please guide me for converting UNICODE (or any format*) text file format into UTF-8 at the time of BEFIMPORT event script
