🌐 Multilingual Support

To ensure all languages render correctly, the app uses Unicode-compatible fonts (e.g., Noto Sans, DejaVu Sans, Amiri, etc.). Fonts are auto-selected based on character sets.

You may extend this by:

• Adding .ttf files for your custom fonts

• Using pdfmetrics.registerFont() to load them

• Dynamically selecting fonts based on language detection (already partially implemented)

Example input
