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.

;  This example program loads a file (japanese.csv)

;  To save the CSV using utf-8 with a BOM/preamble, 
;  add "EMIT_BOM" to the UncommonOptions.
;  (This feature was added in Chilkat v9.5.0.93)

If ($bSuccess <> True) Then
    ConsoleWrite($oCsv.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite("OK, try to load the CSV in Excel to see if the non-English chars are correct." & @CRLF)
