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.

Rust

// 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,"太志","森田"
// 

let csv = chilkat::Csv::new();
csv.set_has_column_names(true);
if csv.load_file2("qa_data/csv/test.csv", "utf-8").is_err() {
    println!("{}", csv.last_error_text());
    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.set_uncommon_options("EMIT_BOM");
if csv.save_file2("qa_output/test.csv", "utf-8").is_err() {
    println!("{}", csv.last_error_text());
    return;
}

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