- Various encoding support
- Edge cases (empty, large, Unicode)
- Special characters handling

**Test Count**: 12 tests

**Key Scenarios**:
- ✅ Default UTF-8 encoding extraction
- ✅ Custom encoding support
- ✅ Error messages include encoding information
- ✅ Large content handling
- ✅ Unicode and special characters
- ✅ Empty and whitespace-only content
