(Ruby) 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,"",""

csv = Chilkat::CkCsv.new()
csv.put_HasColumnNames(true)
success = csv.LoadFile2("qa_data/csv/test.csv","utf-8")
if (success != true)
    print csv.lastErrorText() + "\n";
    exit
end

# 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)

csv.put_UncommonOptions("EMIT_BOM")
success = csv.SaveFile2("qa_output/test.csv","utf-8")
if (success != true)
    print csv.lastErrorText() + "\n";
    exit
end

print "OK, try to load the CSV in Excel to see if the non-English chars are correct." + "\n";
