A program that comparing character coverage across multiple font files.
- Multi-Font Analysis: Upload up to 5 font files (.ttf, .otf) simultaneously
- Unicode Coverage Comparison: Comprehensive character-by-character support matrix
- Interactive Data Table: Sortable, filterable comparison table with real-time updates
- Smart Search: Filter by character, Unicode code (e.g.,
U+4E00,4E00), or text patterns - Visual Font Previews: Live text rendering with each uploaded font
- Export Capabilities: Download results as CSV with robust Unicode handling
- Difference Analysis: Show only characters where fonts differ in support
- Dynamic Sorting: Sort by Unicode, character, coverage count, or individual font support
- Performance Optimized: Handles large CJK fonts efficiently with configurable row limits
- Robust Error Handling: Clear feedback for unsupported files or processing errors
- Responsive UI: Clean, modern interface that works across devices
The application follows a modular, object-oriented design:

- Font Previews: Visual rendering of sample text in each font
Search for specific characters:
- 一 (direct character input)
- U+4E00 (Unicode format)
- 4E00 (hex without prefix)
- CJK (substring search)
- Use row limits (default: 5000) for large font collections
- Enable "Show only differences" to focus on coverage gaps
- Sort by "CoverageCount" to identify most/least supported characters
