The international Character "Ə" doesn't appear in pdf. How can I solve this? please help me

Great post. It worked well with vietnameses characters also. You can take a look at my result at
http://qlkh.tnu.edu.vn/
I converted all documents into pdf in every page

I search a lot of links in google but not found any valuable docs for it.

I want to export pdf file using ITextSharp library that contains Persian, English, Emoji and special

Environment

iTextSharp version: 5.5.10
.NET Core SDK version: 3.1.101
IDE: vs 2019

Example code/Steps to reproduce:

public PdfGenerator( BaseFont bf = null)
{
    _bf = bf ?? BaseFont.CreateFont(Environment.GetEnvironmentVariable("windir") + @"\fonts\iransans.ttf",
              BaseFont.IDENTITY_H, true);

}

var fontNormal = new Font(_bf, 12, Font.NORMAL, BaseColor.Black);

table.AddCell(new PdfPCell(new Phrase(12, text, fontNormal))
{
   RunDirection = PdfWriter.RUN_DIRECTION_RTL,
   BorderWidth = 0,
   Padding = 20,
   Colspan = isLongText ? 3 : 2,
   CellEvent = new RoundedBorder2()
});

It does not support Gujarati language
