## Encoding & Character Handling
All JSON files are written as **UTF-8** with `ensure_ascii=False`. The RSS feed contains Unicode characters (em/en dashes, accented characters) which are preserved correctly in the JSON files.
**If you see mojibake like `â€"` or `é`:**
- The JSON files are correctly stored as UTF-8
- The issue is the *consumer* (text editor, web browser, terminal) reading the file with wrong encoding (Latin-1/Windows-1252)
- **Fix**: Ensure your tools/editor/browser use UTF-8 encoding
**Verification & Repair:**
```bash
# Verify all JSON files are valid UTF-8
python verify_encoding.py
# Fix common mojibake patterns (run if data was corrupted)
python fix_mojibake.py --dry-run # preview fixes
python fix_mojibake.py # apply fixes
# Check progress including encoding status
python check_progress.py
```
**For web apps displaying this data:**
- Set `Content-Type: application/json; charset=utf-8`
- Include `<meta charset="utf-8">` in HTML
- Ensure database connections use UTF-8
