How to get my post title to work with an apostrophe ('s)?

Question

When saving a post with the title Jule's Gormet, it gets formatted as Jule's Gormet. If I save it again, it becomes Jule's Gormet.

Following this pattern, it keeps escaping the ampersand and getting worse.

More info

• WordPress version: 3.3.2
• Theme: http://themetrust.com's Reveal (heavily modified)
• DB is UTF-8
• settings>reading has encoding set to UTF-8
• values are being stored in the database as Jule's (etc..)

I've disabled all plugins and the problem persists.
I've gone through functions.php pretty well, and didn't find anything suspicious. I followed the troubleshooting guide in the brasofilo's comment - but to no effect. Any ideas?

Added this code per tommix

function get_post_title($title) { 
    wp_mail('[email protected]','the title',$title); return $title; 
} add_filter ('title_save_pre','get_post_title');  

Which Yielded these results:

• Jule\'s Gormet - 1st attempt save
• Jule's Gormet - 2nd attempt save
• Jule's Gormet - 3rd attempt save
• Jule's Gormet - 4th attempt save

It actually sent 2 emails per save operation - maybe it means something? idk.

On the Trail!

so, I bit the bullet and started in on a fresh install - using all the edited theme code. After liberally deleting stuff from the functions.php, I found the issue is somehow related to Bainternet's Tax-meta-class I'm using to add a field to one of my custom taxonomies. Removing the following code fixes the issue. (though I'd like to figure out how to fix it while retaining my added taxonomy field.

// CUSTOM TAXONOMY FIELDS
require_once("Tax-meta-class/Tax-meta-class.php");
$config = array(
   'id' => 'focus_creative_services',
   'title' => 'creative services',
   'pages' => array('focus'),
   'context' => 'normal',
   'fields' => array(),
   'local_images' => false,
   'use_with_theme' => true
);
$creative_services_meta = new Tax_Meta_Class($config);
$creative_services_meta->addTextarea('textarea_field_id',array('name'=> 'Creative Services '));
$creative_services_meta->Finish();

I dropped a note to @Bainternet on his websites FAQ. Hopefully he'll sort me out.

EDIT:

Disable magic_quotes_gpc in your server. try adding in .HTACCESS file (if you on shared hosting): php_flag magic_quotes_gpc off If you'll get 500 server error after you added it - delete it and put this: ini_set ('magic_quotes_gpc', 0); in theme's functions.php file. And with function bellow check is it on.

You can create php file with this content to test is it on (if on you'll see this nice string):

if (get_magic_quotes_gpc()) {
    echo 'F@ck.. its on :D';
}

2nd try: If the magic quotes was ok, than MAYBE you can try and search in your plugins, and theme's php files (with textcrawler) do some of them uses stripslashes function on title?
