# Complex Markdown Document

This document tests various markdown features with editing capabilities.

## Text Formatting

This paragraph contains **bold text**, *italic text*, and `inline code`.
It also has [a link](https://example.com) and some regular text.

### Lists and Code

Here's an unordered list:
- First item with **bold**
- Second item with *italic*
- Third item with `code`

And an ordered list:
1. First numbered item
2. Second numbered item
3. Third numbered item

```python
def example_function():
    \"\"\"This is a code block that should be editable.\"\"\"
    return "Hello, World!"
```

### Tables and Quotes

| Column 1 | Column 2 | Column 3 |
|----------|----------|----------|
| Data 1   | Data 2   | Data 3   |
| More 1   | More 2   | More 3   |

> This is a blockquote that should be editable.
> It can span multiple lines and contain *formatting*.

### Special Characters and Unicode

Testing unicode: 你好 🌍 ñoño café résumé

```javascript
// More code with special characters
const message = "Hello, 世界!";
console.log(message);
```

## Final Section

This is the final section for testing.
