(Swift 2) 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.

func chilkatTest() {
    // 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,"",""
    // 

    let csv = CkoCsv()
    csv.HasColumnNames = true
    var success: Bool = csv.LoadFile2("qa_data/csv/test.csv", charset: "utf-8")
    if success != true {
        print("\(csv.LastErrorText)")
        return
    }

    // 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.UncommonOptions = "EMIT_BOM"
    success = csv.SaveFile2("qa_output/test.csv", charset: "utf-8")
    if success != true {
        print("\(csv.LastErrorText)")
        return
    }

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