# Arabic Fonts Installation Fix for Ubuntu 22.04

## Problem Identified
The Docker build was failing because:
1. `fonts-scheherazade-new` is not available in Ubuntu 22.04
2. `fonts-scheherazade` is also not available in Ubuntu 22.04

## Root Cause
Ubuntu 22.04 (jammy) does not include the Scheherazade font packages in its official repositories.

## Solution Implemented
1. **Used Available Arabic Fonts**: Replaced unavailable font packages with officially available ones:
   - `fonts-noto-naskh-arabic`
   - `fonts-noto-kufi-arabic`
   - `fonts-hosny-amiri`

2. **Manual Font Installation**: Added direct download of Scheherazade New font from Google Fonts repository:
   ```dockerfile
   RUN mkdir -p /usr/share/fonts/truetype/scheherazade \
       && wget -q https://github.com/google/fonts/raw/main/ofl/scheherazadenew/ScheherazadeNew-Regular.ttf -O /usr/share/fonts/truetype/scheherazade/ScheherazadeNew-Regular.ttf \
       && wget -q https://github.com/google/fonts/raw/main/ofl/scheherazadenew/ScheherazadeNew-Bold.ttf -O /usr/share/fonts/truetype/scheherazade/ScheherazadeNew-Bold.ttf \
       && fc-cache -fv
   ```

## Changes Made

### Dockerfile
- Removed unavailable font packages (`fonts-scheherazade-new`, `fonts-scheherazade`)
- Added available Arabic font packages for Ubuntu 22.04
- Added manual installation of Scheherazade New font from Google Fonts
- Kept all other packages and configuration the same

## Expected Results
These changes should resolve the build error and provide comprehensive Arabic font support:

✅ **Build Success**: Docker image will build without font package errors
✅ **Arabic Support**: Multiple Arabic fonts available for document rendering
✅ **Scheherazade New**: Manually installed for users who specifically need this font
✅ **Compatibility**: Maintained Ubuntu 22.04 base image for Hugging Face Spaces compatibility

## Font Options Now Available
1. **Noto Naskh Arabic** - General Arabic text rendering
2. **Noto Kufi Arabic** - Modern Arabic UI text
3. **Amiri** - Classical Arabic typography
4. **Scheherazade New** - Manually installed from Google Fonts
5. **Liberation Fonts** - Latin text with Arabic support
6. **DejaVu Fonts** - Extended character set support

## Verification Steps
1. Rebuild the Docker image
2. Verify the image builds without errors
3. Check that all fonts are properly installed:
   ```bash
   fc-list | grep -i arabic
   fc-list | grep -i scheherazade
   fc-list | grep -i amiri
   ```
4. Test document conversion with Arabic text

## Additional Benefits
- Better font diversity for Arabic document rendering
- Fallback options if one font is not available
- Manual installation ensures latest font versions
- No dependency on Ubuntu repository availability
