PDF Khmer Unicode Font Not Rendering Correctly #1264
Description
Hello everyone,
I'm using Eclipse BIRT Report Designer to generate reports in PDF format, but I’m facing issues with rendering Khmer Unicode Font. The Khmer characters either:
- Appear as blank or missing text, or
- Show incorrect khmer characters.
I've tested generating a simple PDF using OpenPDF with the Hanuman font. Here’s the code I used:
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Font;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.BaseFont;
import com.lowagie.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
public class Main {
public static void main(String[] args) throws DocumentException, IOException {
// Output PDF file
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream("Khmer_Font_Test.pdf"));
} catch (DocumentException | FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
document.open();
// Load Hanuman TTF font
BaseFont hanumanFont = BaseFont.createFont("/Users/sinsarath/eclipse-workspace/SamplePdf/fonts/Hanuman.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font = new Font(hanumanFont, 14); // Set font size to 14
// Add Khmer text
String khmerText = "លេខ";
document.add(new Paragraph(khmerText, font));
document.close();
System.out.println("PDF generated successfully!");
}
}
Result are render not correct:
It should be displayed like that: លេខ
