 //   * The output encoding will be UTF-8. No code points will be escaped.
 //   * Lines will be separated by the platform-specific EOL terminator.
 //   * Values will be enclosed in double-quotes if and only if they contain
 //     either of the following characters: CR, LF, double-quote ("), comma (,).
 //
 // The CSV representation of the supplied data will be generated into |csv|,
 // which is first cleared of pre-existing data. The first line of the file will
 // contain |column_names|, followed by as many lines as there are elements in
 // |records|. Each element in |records| should be a dictionary that maps column
 // names to values, so they can be output in the right order. All passed in
 // strings should be UTF-8 encoded.
