It seems that you are encountering an issue with creating a PDF using Aspose.PDF (version 22.5) when your DataTable contains special characters. This can often lead to problems if the characters are not properly handled or if the font being used does not support them.

Here are a few steps you can take to troubleshoot and potentially resolve the issue:

  1. Check Font Support: Ensure that the font you are using supports the special characters in your text. If the font does not support these characters, the PDF may fail to generate. You can try using a different font that is known to support a wider range of characters, such as Arial Unicode MS or a similar font.

  2. Encoding Issues: Make sure that the text being added to the PDF is properly encoded. If you are pulling data from a database or another source, ensure that the encoding is consistent and supports the special characters.

  3. Error Handling: Implement error handling in your code to catch any exceptions that may occur during the PDF generation process. This can help you identify the specific issue causing the PDF not to be created.

  4. Simplify the Input: As a test, try creating a PDF with a simpler string that does not contain special characters. If this works, it confirms that the issue is related to the special characters in your original string.

  5. Update Aspose.PDF: If possible, consider updating to a newer version of Aspose.PDF. There may have been bug fixes or improvements related to character handling in later versions.

Here is a sample code snippet that demonstrates how to add text to a PDF while ensuring proper handling of special characters:

using Aspose.Pdf;
using Aspose.Pdf.Text;

// Create a new document
Document pdfDocument = new Document();
Page pdfPage = pdfDocument.Pages.Add();

// Create a table
Table table = new Table();
pdfPage.Paragraphs.Add(table);

// Loop through the DataTable
foreach (DataRow row in datatable.Rows)
{
    Row dataRow = table.Rows.Add();
    foreach (DataColumn column in datatable.Columns)
    {
        Cell dataCell = dataRow.Cells.Add();
        // Ensure the text is properly encoded
        string cellText = row[column].ToString();
        dataCell.Paragraphs.Add(new TextFragment(cellText));
        dataCell.Alignment = HorizontalAlignment.Left;
    }
}

// Save the document
pdfDocument.Save("output.pdf");

By following these steps and using the provided code snippet, you should be able to troubleshoot the issue with PDF creation. If the problem persists, consider reaching out to Aspose support for further assistance.
