- Bold, italic, and underline text
- Text color (RTF color table and \cfN codes)
- Unicode characters (e.g. \u237?)
- Bulleted and numbered lists
- Paragraph and line break handling
- Non-breaking spaces
Cleans up empty paragraphs and extra whitespace
Compatible with both JavaScript and TypeScript projects (includes type definitions)
Outputs HTML using <div>, <strong>, <em>, <u>, <span style="color:...">, <ul>, <li>, etc.

Limitations / Known Issues

Does not support RTF tables, images, or embedded objects.
Only basic text formatting is supported (bold, italic, underline, color, lists, paragraphs).
Font face and font size are ignored.
Complex nested RTF structures may not be fully converted.
Only the color table defined in the RTF is used for color conversion.
Output is intended for display, not for round-trip editing back to RTF.
