(Tcl) 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)
# that contains this content:
# 
# year,color,country,food
# 2001,red,France,cheese
# 2005,blue,"United States",hamburger
# 2008,green,Italy,pasta
# 1998,orange,Japan,sushi
# 2010,silver,"",""

set csv [new_CkCsv]

CkCsv_put_HasColumnNames $csv 1

if {$success != 1} then {
    puts [CkCsv_lastErrorText $csv]
    delete_CkCsv $csv
    exit
}

# 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)

CkCsv_put_UncommonOptions $csv "EMIT_BOM"
set success [CkCsv_SaveFile2 $csv "qa_output/test.csv" "utf-8"]
if {$success != 1} then {
    puts [CkCsv_lastErrorText $csv]
    delete_CkCsv $csv
    exit
}

puts "OK, try to load the CSV in Excel to see if the non-English chars are correct."
