The Pandoc HTML reader is, perhaps surprisingly, worse for reading HTML
than the Markdown reader, which will generally preserve HTML (because
Markdown is defined as a superset of HTML). So if you want to read HTML
without erasing stuff, you are generally better off specifying the
*Markdown* reader. The results can be kinda ugly, but there's no way around
it: there is no 'native' Markdown for a checkbox input, so it uses the
fallback.

Example:

    $ echo '<p><input type="checkbox" /></p>' | pandoc -f html -w markdown
    $ echo '<p><input type="checkbox" /></p>' | pandoc -f markdown -w
markdown
    ```{=html}
    <p>
    ```
    `<input type="checkbox" />`{=html}
    ```{=html}
    </p>
    ```

The HTML reader can't understand the <input> so it is silently dropped. The
Markdown reader treats it as a HTML fragment embedded in Markdown, which is
preserved as a literal, and passed through.
