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 flutter khmer pdf updated

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:

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 create a guide for handling Khmer text in Flutter PDF generation, you must address a specific technical challenge: most PDF libraries do not natively support the complex rendering required for Khmer Unicode (such as sub-scripts and vowel positioning). 1. Essential Tools & Packages You will need the following updated packages from pub.dev:

pdf: The core library for creating PDF files in Dart/Flutter.

printing: To display or print the generated PDF within the app.

path_provider: To find the correct storage paths for saving the PDF on a device. 2. The Font Requirement (Critical)

Standard PDF fonts do not support Khmer characters. You must bundle a Khmer Unicode font (like Khmer OS Battambang or Kantumruy) in your project assets. Asset Setup: Add the font to your pubspec.yaml.

flutter: fonts: - family: KhmerOS fonts: - asset: assets/fonts/KhmerOS.ttf Use code with caution. Copied to clipboard

Implementation: Load the font as a pw.Font object before generating the text. 3. Step-by-Step Implementation Guide

Initialize the Document: Create a new PDF document using the pdf package.

Load the Custom Font: Use rootBundle to load your Khmer font so the PDF engine knows how to draw the glyphs.

final khmerFont = pw.Font.ttf(await rootBundle.load("assets/fonts/KhmerOS.ttf")); Use code with caution. Copied to clipboard

Apply Text Styling: When creating a pw.Text widget, you must explicitly set the font in the TextStyle. If you don't, the Khmer characters will appear as empty boxes or "tofu".

pw.Text( 'សួស្តីពិភពលោក', // Hello World in Khmer style: pw.TextStyle(font: khmerFont, fontSize: 20), ); Use code with caution. Copied to clipboard Save or Display:

Save: Use getApplicationDocumentsDirectory() to get a safe path and write the bytes to a file.

Preview: Use the PdfPreview widget from the printing package for an instant in-app view. 4. Common Troubleshooting

Glyph Rendering Errors: If complex clusters (like ្ក) don't render correctly, ensure you are using the latest version of the pdf package, as support for complex scripts is frequently updated.

Font Fallback: If mixing Khmer and English, use fontFallback in your TextStyle to ensure both scripts render correctly even if one font doesn't support all characters.
