Using the DBF library, I am trying to create a converter from a CSV file to DBF. The conversion should take place on the browser side. I have a problem – the Cyrillic characters are not displayed correctly in the created dbf file. I tried many options, but nothing worked.
csv file can have different encodings

  const [csvData, setCsvData] = useState(null);
  const handleFileUpload = (event) => {
    const file = event.target.files[0];
    if (file) {
      const reader = new FileReader();
      reader.onload = (e) => {
        const text = e.target.result;
        const result = parse(text, { header: true });
        setCsvData(result.data);
      };
      reader.readAsText(file);
    }
  };
  const convertToDBF = () => {
    if (csvData) {
      try {
        const fields = Object.keys(csvData[0]).map(key => ({
          name: key,
          type: 'C',
          size: 10
        }));  
        const records = csvData.map(row => {
          const record = {};
          Object.keys(row).forEach(key => {
            record[key] = row[key] ? row[key].toString() : ''; 
          });  
          for (const key in record) {
            if (typeof record[key] === 'string') {
              record[key] = iconv.encode(record[key], 'UTF-8'); 
            }     }
          return record;
        });
        const dbfBuffer = structure(records, fields);
        const blob = new Blob([dbfBuffer], { type: 'application/octet-stream' });
        saveAs(blob, 'output.dbf');
      } catch (error) {
        console.error('Error during DBF conversion:', error);
      }
    }
  };

  return (
    <div>
      
      <input type="file" accept=".csv" onChange={handleFileUpload} />
      <button onClick={convertToDBF} disabled={!csvData}>to DBF</button>
    </div>
  );
};

export default App;```



I tried to change the encodings. I expect a readable display of Cyrillic characters
