当使用itextsharp在c＃中阅读marathi pdf时，它没有显示来自pdf的正确文本？

Question

我试图在c＃中使用itextsharp阅读marathi pdf，但我没有正确获取数据。 当我通过c＃阅读马拉地语pdf时，会注意显示正确的数据。

    public string ReadPdfFile(string fileName)
    {
        StringBuilder text = new StringBuilder();

        if (System.IO.File.Exists(fileName))
        {
            PdfReader pdfReader = new PdfReader(fileName);
            Workbook workbook = new Workbook();

            //workbook.LoadFromFile("F:/finalexcel.xls");
            Worksheet sheet = workbook.Worksheets[0];
            sheet.Range["A1"].Text = "ओळखपत्र क्रमांक";
            sheet.Range["B1"].Text = "मतदाराचे पुर्ण नाव";
            sheet.Range["C1"].Text = "वडिलांचे नाव";
            sheet.Range["D1"].Text = "घर क्रमांक";
            sheet.Range["E1"].Text = "वय";
            sheet.Range["F1"].Text = "लिंग ";
            for (int page =1; page <= pdfReader.NumberOfPages; page++)
            {
                ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
                //ITextExtractionStrategy strategy = new LocationTextExtractionStrategy();
                string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);

                //string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);
                currentText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Unicode, Encoding.Unicode, Encoding.UTF8.GetBytes(currentText)));
                //MessageBox.Show(currentText);

                //string[] b = currentText.Split("लऱंग").ToString();
                //  string[] b = currentText.Split('\n');
                foreach (var item in a)
                {
                    //MessageBox.Show(item);
                    if (item.Contains(":"))
                    {
                        string[] sample = item.Split(':');
                        if (sample[1].Length > 1 && sample[0].Contains("मतदार"))
                        {
