• Font replacement strategies: Replace fonts while maintaining layout
• Unicode handling: Manage special characters and symbols

2. Advanced Text Flow Control

Manipulate text flow for complex layouts:

• Text reflow algorithms: Automatically adjust text to fit new layouts
• Column balancing: Distribute text evenly across columns
• Hyphenation control: Manage word breaks and hyphenation
• Kerning and tracking: Fine-tune character and word spacing

3. OCR Enhancement and Correction

Improve OCR results for scanned documents:

1. Pre-processing: Enhance image quality before OCR
2. Multiple OCR engines: Compare results from different engines
3. Manual correction: Systematic approach to fixing OCR errors
4. Confidence scoring: Identify and prioritize uncertain text
