urdu_pdf_fixer

Unicode-first Urdu text rendering for PDFs generated with Flutter's pdf package.

This package is a thin language-focused facade over pdf_text_shaper. HarfBuzz performs real OpenType shaping while this package adds convenient font loading, script detection and PDF widgets.

Features

• Unicode-first Urdu text
• fallback fonts for mixed-script documents
• multiline wrapping and reusable typography
• optional invisible Unicode layer for search/copy

• RTL-friendly defaults for text alignment, lists, rich text and tables
• no bundled fonts
