Stop wordpress from “correcting” my code?

Question

I'm starting to lose my patience with Wordpress. I've downloaded a raw html plugin that should stop wordpress from converting some characters to their entities, I won't use the visual editor but still, every once and a while, it messes up my code. It converts < and > to < and > from some parts of the code and leaves me wondering where the problem is. I'm using 3.4.2, and I'm wondering if there's a way to COMPLETELY stop wordpress from editing my stuff. I mean no automatic paragraphs, no character converting, etc.

First off, make sure you use the HTML editor in the post screen instead of the visual.

Second, take a look in wp-includes/default-filters.php. It's where you can see how WordPress uses its own hooks API. The stuff that deals with things in the content of posts will be hooked into the_content. Here's the relevant bit.

<?php
add_filter( 'the_content', 'wptexturize'        );
add_filter( 'the_content', 'convert_smilies'    );
add_filter( 'the_content', 'convert_chars'      );
add_filter( 'the_content', 'wpautop'            );
add_filter( 'the_content', 'shortcode_unautop'  );
add_filter( 'the_content', 'prepend_attachment' );

So if you don't want autop or convert_chars, you could could remove it (this should probably go in a plugin). Something like this:

<?php
// Hook into init to make sure the filter is there to remove.
add_action('init', 'wpse66038_remover');
function wpse66038_remover()
{
   remove_filter('the_content', 'wpautop');
   remove_filter('the_content', 'convert_chars');
}
