itextPDF 8 to generate pdf with emoji font support

I'm trying to find out a way to create pdf with emoji fonts support by using itextpdf 8.0.3.

I only found an example that came from itextpdf official website; https://kb.itextpdf.com/itext/pdfhtml-using-emojis-in-itext but it is talking about create pdf from html source.

I found an other example on Internet such as: https://kodejava.org/how-do-i-display-emoji-in-a-pdf-document-using-itext-8/.

There are some code as:

package org.kodejava.itext;

import com.itextpdf.io.font.PdfEncodings;
import com.itextpdf.kernel.colors.DeviceRgb;
import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.kernel.font.PdfFont;
import com.itextpdf.kernel.font.PdfFontFactory;
import com.itextpdf.layout.Document;
import com.itextpdf.layout.element.Paragraph;

import java.io.IOException;

public class DocumentWithEmoji {
  public static void main(String[] args) throws IOException {
    PdfWriter writer = new PdfWriter("emoji.pdf");
    PdfDocument pdf = new PdfDocument(writer);

    try (Document document = new Document(pdf)) {
        PdfFont fontEmoji = PdfFontFactory.createFont("seguiemj.ttf", PdfEncodings.IDENTITY_H);

        Paragraph paragraph = new Paragraph()
                .add(new Paragraph("Hello ").setFont(fontEmoji).setFontSize(20))
                .add(new Paragraph("\uD83D\uDE00").setFont(fontEmoji).setFontSize(20)
                        .setFontColor(new DeviceRgb(243, 58, 106)));

        document.add(paragraph);
    } catch (Exception e) {
        e.printStackTrace();
    }
  }
}

expected return should be:

enter image description here

but I got it as:

enter image description here

As you can see, it shows as red round dish instead of a red smile face.

Does anyone have such experience? if you do, please share some idea with me.
