I need to extractmalayalam text from pdf.While extracting the text with itextsharp text extraction strategy some special characters are also coming with the text.

What I have tried:

I HAVE TRIED THIS
PdfReader pdfReader = new PdfReader(fileName);

for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);

text.Append(currentText);
}
pdfReader.Close();

I HAVE ALSO TRIED
byte[] bytes = Encoding.UTF8.GetBytes(ParseText);
byte[] converted = Encoding.Convert(Encoding.Default, Encoding.UTF8, bytes);
string final = Encoding.UTF8.GetString(converted);

See How to extract text from PDF file with IDENTITY-H fonts using VB.NET - Stack Overflow[^]
When looking at the example there, I think there might be some possibility of reverse engineering the specific "identity h encoding" of your file. Get the bytes of the text first (byte[] bytes = Encoding.UTF8.GetBytes(ParseText);), but then use your own custom converter which changes some bytes to the correct values for Malayalam characters. It is your job to find out how they are mapped.
