Khmer text renders incorrectly in PDF · Issue #1873 - GitHub
Describe the bug. When generating a PDF that contains Khmer Unicode text using the pdf package, the output text is rendered incorrectly — Khmer combining marks (su Modern Khmer PDF Generation in Flutter
Implementing Khmer language support in Flutter PDF generation requires moving beyond standard system fonts to specialized Unicode libraries. The most common modern libraries for this purpose include the community-maintained pdf package (often used with ) and the commercial Syncfusion Flutter PDF library Dart packages Primary Use Case Enterprise-grade documents, complex forms, and secure PDFs. Primary Use Case Lightweight, community-driven projects and resumes. Unicode Handling PdfTrueTypeFont to map specific glyphs for Unicode. Unicode Handling Requires manual loading of TTF files like Battambang-Regular Native Dart implementation with broad platform support.
Highly customizable with widgets similar to standard Flutter UI. Core Implementation Strategies
The updated workflow for supporting Khmer text centers on ensuring the rendering engine can access the correct glyphs. Font Embedding:
standard fonts like Helvetica do not support Unicode characters. You must embed a Khmer-specific font (e.g., Battambang or Noto Khmer) by loading the file from your assets folder or using the GoogleFonts Initial Font Loading:
For libraries that fetch fonts at runtime, such as the Google Fonts package, it is recommended to start the download during the
to ensure the font is available before the PDF generation logic triggers. Global Theming:
To avoid manually assigning fonts to every text widget, you can create a global
for your PDF document, ensuring all text elements automatically inherit the Khmer-compatible font. Overcoming Rendering Challenges
Even with the correct fonts, Khmer script presents unique challenges due to its complex diacritical marks and consonant clusters. The "Coeng" Sign Issue: តើ Flutter ជាអ្វី
A recurring bug in Khmer PDF rendering is the failure of the "Khmer Sign Coeng" (្)
to combine correctly with preceding and following letters, leading to unreadable clusters. Text Shaping:
To fix misplaced subscript characters, modern implementation requires text shaping
. Using a shaping engine (like HarfBuzz) helps the software understand how to correctly position Khmer glyphs based on the script and language. Platform Specifics:
While older Android versions (pre-4.4.4) struggled with Khmer Unicode rendering, modern versions and the flutter_html_to_pdf plugin
often provide more reliable results by leveraging platform-native rendering engines. Stack Overflow Learn more Saved time Comprehensive Inappropriate Not working A copy of this chat will be included with your feedback

To work with Khmer text in Flutter PDFs, the most critical requirement is using a TrueType Font (.ttf) that supports Khmer Unicode. Standard PDF fonts do not support these characters, which often results in blank spaces or errors like "Can not decode to Latin1". 🛠️ Required Packages
You will typically need these two libraries added to your pubspec.yaml: pdf: For generating the document structure. path_provider: To save the generated file to the device. 📝 Step-by-Step Implementation Prepare the Khmer Font
Download a Khmer Unicode font (e.g., Khmer OS Battambang or Hanuman). Place the .ttf file in your project's assets/fonts/ folder. Declare it in your pubspec.yaml.
Load the Font in CodeYou must load the font as a Font object before using it in the PDF Text widget.
final fontData = await rootBundle.load("assets/fonts/KhmerOS_Battambang.ttf"); final ttf = pw.Font.ttf(fontData); Use code with caution. Copied to clipboard
Generate the PDF with Khmer TextEnsure you apply the loaded font to a TextStyle.
final pdf = pw.Document(); pdf.addPage( pw.Page( build: (pw.Context context) => pw.Center( child: pw.Text( "សួស្តីពិភពលោក", // "Hello World" in Khmer style: pw.TextStyle(font: ttf, fontSize: 40), ), ), ), ); Use code with caution. Copied to clipboard 💡 Key Tips for Khmer Support
UTF-8 Encoding: Always ensure your source files and data are stored in UTF-8 format.
HTML to PDF: If you prefer using HTML templates, the flutter_html_to_pdf_v2 package supports Khmer Unicode if you declare in your HTML.
Syncfusion PDF: For advanced features like RTL support or complex tables, syncfusion_flutter_pdf is a robust enterprise-grade alternative. 📂 Saving the File
Use the path_provider to find a safe location on the device to store the PDF:
final directory = await getApplicationDocumentsDirectory(); final file = File("$directory.path/khmer_report.pdf"); await file.writeAsBytes(await pdf.save()); Use code with caution. Copied to clipboard
