This isn't very sophisticated but does a few things in a simple-minded way.

This is an example of converting plain text to HTML which demonstrates extracting a title and escaping certain characters within bulleted and numbered lists.
* This is a bulleted list with a less than sign (<)
* And this is its second line with a greater than sign (>)
A 'normal' paragraph between the lists.
1. This is a numbered list with an ampersand (&)
2. "Second line" in double quotes
3. 'Third line' in single quotes
That's all folks.`
