(DataFlex) Write utf-8 CSV Compatible with Excel

See more CSV Examples

A CSV containing non-English characters that is saved using the utf-8 character encoding must include a BOM (also known as a preamble) if it is to be correctly loaded into Excel. See https://en.wikipedia.org/wiki/Byte_order_mark

This example shows how to save the CSV to a file using utf-8 with a BOM.

Note: This example requires Chilkat v9.5.0.93 or later.
